classica These motors use a 50cc,

Super Cub was developed over three years, so cheap and easy to be ridden by anyone. These motors use a 50cc, OHC, 4 stroke, centrifugal clutch with three speed transmission. This motor is very easy to drive, .. even for beginners though. This form is known as a duck now ... became popular in his day. Women also easy to drive it .. because do not need to be hampered by existing forms of conventional motor gasoline tank etc ...! This motor is then up ... there are different versions of 50cc, 70cc and 90cc ...! In 1959, Honda began exporting and entering the U.S. market ...! And related to this bike ... in late December 2005, this bike has been produced as many as 50 million units

Mikuni carburetor Motorcycle

Mikuni Motorcycle Carburetor

Motorcycle carburetors look very complex, but with a little theory, you can tune your bike for maximum performance. All carburetors work under the basic principle of atmospheric pressure. Atmospheric pressure is a powerful force which exerts pressure on everything. It varies slightly but is generally considered to be 15 pounds per square inch (PSI). This means that atmospheric pressure is pressing on everything at 15 PSI. By varying the atmospheric pressure inside the engine and carburetor, we can change the pressure and make fuel and air flow.

Atmospheric pressure will force high pressure to low pressure. As the piston on a two stroke engine goes up (or goes down on a four stroke engine), a low pressure is formed inside the crankcase (above the piston on a four stroke). This low pressure also causes a low pressure inside the carburetor. Since the pressure is higher outside the engine and carburetor, air will rush inside the carburetor and engine until the pressure is equalized. The moving air going through the carburetor will pick up fuel and mix with the air.

Inside a carburetor is a venturi, fig 1. The venturi is a restriction inside the carburetor that forces air to speed up to get through. A river that suddenly narrows can be used to illustrate what happens inside a carb. The water in the river speeds up as it gets near the narrowed shores and will get faster if the river narrows even more. The same thing happens inside the carburetor. The air that is speeding up will cause atmospheric pressure to drop inside the carburetor. The faster the air moves, the lower the pressure inside the carburetor. 

FIG 1

Most motorcycle carburetor circuits are governed by throttle position and not by engine speed.There are five main metering systems inside most motorcycle carburetors. These metering circuits overlap each other and they are:
* pilot circuit
* throttle valve
* needle jet and jet needle
* main jet
* choke circuit

The pilot circuit has two adjustable parts, fig 2. The pilot air screw and pilot jet. The air screw can be located either near the back side of the carburetor or near the front of the carburetor. If the screw is located near the back, it regulates how much air enters the circuit. If the screw is turned in, it reduces the amount of air and richens the mixture. If it is turned out, it opens the passage more and allows more air into the circuit which results in a lean mixture. If the screw is located near the front, it regulated fuel. The mixture will be leaner if it is screwed in and richer if screwed out. If the air screw has to be turned more than 2 turns out for best idling, the next smaller size pilot jet will be needed. 

FIG 2

The pilot jet is the part which supplies most of the fuel at low throttle openings. It has a small hole in it which restricts fuel flow though it. Both the pilot air screw and pilot jet affects carburetion from idle to around 1/4 throttle.

The slide valve affects carburetion between 1/8 thru 1/2 throttle. It especially affects it between 1/8 and 1/4 and has a lesser affect up to 1/2. The slides come in various sizes and the size is determined by how much is cutaway from the backside of it, fig 3. The larger the cutaway, the leaner the mixture (since more air is allowed through it) and the smaller the cutaway, the richer the mixture will be. Throttle valves have numbers on them that explains how much the cutaway is. If there is a 3 stamped into the slide, it has a 3.0mm cutaway, while a 1 will have a 1.0mm cutaway (which will be richer than a 3). 

FIG 3

The jet needle and needle jet affects carburetion from 1/4 thru 3/4 throttle. The jet needle is a long tapered rod that controls how much fuel can be drawn into the carburetor venturi. The thinner the taper, the richer the mixture. The thicker the taper, the leaner the mixture since the thicker taper will not allow as much fuel into the venturi as a leaner one. The tapers are designed very precisely to give different mixtures at different throttle openings. Jet needles have grooves cut into the top. A clip goes into one of these grooves and holds it from falling or moving from the slide. The clip position can be changed to make an engine run richer or leaner, fig 4. If the engine needs to run leaner, the clip would be moved higher. This will drop the needle farther down into the needle jet and cause less fuel to flow past it. If the clip is lowered, the jet needle is raised and the mixture will be richer.

The needle jet is where the jet needle slides into. Depending on the inside diameter of the needle jet, it will affect the jet needle. The needle jet and jet needle work together to control the fuel flow between the 1/8 thru 3/4 range. Most of the tuning for this range is done to the jet needle, and not the needle jet. 

FIG 4

The main jet controls fuel flow from 3/4 thru full throttle, fig 5. Once the throttle is opened far enough, the jet needle is pulled high enough out of the needle jet and the size of the hole in the main jet begins to regulate fuel flow. Main jets have different size holes in them and the bigger the hole, the more fuel that will flow (and the richer the mixture). The higher the number on the main jet, the more fuel that can flow through it and the richer the mixture.

FIG 5

The choke system is used to start cold engines. Since the fuel in a cold engine is sticking to the cylinder walls due to condensation, the mixture is too lean for the engine to start. The choke system will add fuel to the engine to compensate for the fuel that is stuck to the cylinder walls. Once the engine is warmed up, condensation is not a problem, and the choke is not needed.

The air/fuel mixture must be changes to meet the demands of the needs of the engine. The ideal air/fuel ratio is 14.7 grams of air to 1 gram of fuel. This ideal ratio is only achieved for a very short period while the engine is running. Due to the incomplete vaporization of fuel at slow speeds or the additional fuel required at high speeds, the actual operational air/fuel ratio is usually richer. Figure 6 shows the actual air/fuel ratio for any given throttle opening.

FIG 6

Carburetor Jetting Troubleshooting

Carburetor troubleshooting is simple once the basic principles are known. The first step is to find where the engine is running poorly, fig 7. It must be remembered that carburetor jetting is determined by the throttle position, not engine speed. If the engine is having troubles at low rpm (idle to 1/4 throttle), the pilot system or slide valve is the likely problem. If the engine has problems between 1/4 and 3/4 throttle, the jet needle and needle jet (most likely the jet needle) is likely the problem. If the engine is running poorly at 3/4 to full throttle, the main jet is the likely problem.

FIG 7

While jetting carburetors, place a piece of tape on the throttle housing. Place another piece of tape on the throttle grip and draw a line (while the throttle is at idle) straight across from one piece of tape to the other. When these two lines are lined up, the engine will be idling. Now open the throttle to full throttle and draw another line directly across from it on the throttle housing. At this point, there should be two lines on the throttle housing, and one on the throttle grip. Now find the half-way point between both of the lines on the throttle housing. Make a mark and this will show when the throttle is at half throttle. Divide the spaces up even again until idle, 1/4, 1/2, 3/4, and full throttle positions are known. These lines will be used to quickly find the exact throttle opening while jetting.

Clean the air filter and warm the bike up. Accelerate through the gears until the throttle is at full throttle (a slight uphill is the best place for this). After a few seconds of full throttle running, quickly pull in the clutch and stop the engine (Do not allow the engine to idle or coast to a stop). Remove the spark plug and look at its color. It should be a light tan color (for more info on reading spark plugs click here). If it's white, the air/fuel mixture is too lean and a bigger main jet will have to be installed. If it's black or dark brown, the air/fuel mixture is too rich and a smaller main jet will have to be installed. While changing jets, change them one size at a time, test run after each change, and look at the plug color after each run.

After the main jet has been set, run the bike at half throttle and check the plug color. If it's white, lower the clip on the jet needle to richen the air/fuel mixture. If it's dark brown or black, raise the clip to lean the air/fuel mixture.

The pilot circuit can be adjusted while the bike is idling and then test run. If the engine is running poorly just off of idle, the pilot jet screw can be turned in or out to change the air-fuel mixture. If the screw is in the back of the carburetor, screwing it out will lean the mixture while screwing it in will richen it. If the adjustment screw is in the front of the carburetor, it will be the opposite. If turning the screw between one and two and a half doesn't have any affect, the pilot jet will have to be replaced with either a larger or smaller one. While adjusting the pilot screw, turn it 1/4 turn at a time and test run the bike between adjustments. Adjust the pilot circuit until the motorcycle runs cleanly off of idle with no hesitations or bogs.

Altitude, Humidy, and Air Temperature

Once the jetting is set and the bike is running good, there are many factors that will change the performane of the engine. Altitude, air temperature, and humidity are big factors that will affect how an engine will run. Air density increases as air gets colder. This means that there are more oxygen molecules in the same space when the air is cold. When the temperature drops, the engine will run leaner and more fuel will have to be added to compensate. When the air temperature gets warmer, the engine will run richer and less fuel will be needed. An engine that is jetted at 32deg Fahrenheit may run poorly when the temperature reaches 90deg Fahrenheit.

Altitude affects jetting since there are less air molecules as altitude increases. A bike that runs good at sea level will run rich at 10,000 ft due to the thinner air.

Humidity is how much moister is in the air. As humidity increases, jetting will be richer. A bike that runs fins in the mornings dry air may run rich as the day goes on and the humidity increases.

Correction factors are sometimes used to find the correct carburetor settings for changing temperatures and altitudes. The chart in fig 8, shows a typical correction factor chart. To use this chart, jet the carburetor and write down the pilot and main jet sizes. Determine the correct air temperature and follow the chart over to the right until the correct elevation is found. Move straight down from this point until the correct correction factor is found. Using fig 8 as an example, the air temperature is 95deg Fahrenheit and the altitude is 3200 ft. The correction factor will be 0.92. To find out the correction main and pilot jets, multiple the correction factor and each jet size. A main jet size of 350 would be multiplied by 0.92 and the new main jet size would be a 322. A pilot jet size of 40 would be multiplied by 0.92 and the pilot jet size would be 36.8.

FIG 8

Correction factors can also be used to find the correct settings for the needle jet, jet needle, and air screw. Use the chart from fig 9 and determine the correction factor. Then use the table below to determine what to do with the needle jet, jet needle, and air screw.

Needle Jet/Jet Needle/Air Screw Correction Chart

Correction factor	1.04 or above	1.04-1.00	1.00-0.96	0.96-0.92	0.92 or below
Needle jet	Two sizes larger	One size larger	Same size	One size smaller	Two sizes smaller
Jet needle setting	Lower clip position	Same	Same	Same	Raise clip one position
Air screw opening	One turn in	1/2 turn in	Same	1/2 turn out	One turn out

Want to Try Gasoline economicalSaturday's service again in the same place only different mechanics. I'm saving the carburetor is set. The result is still 1:25. But I see it, it remains stationary frequency can be lowered so I experimented again. I changed the air valve and faucet just gasoline. At Mikuni carburetors, the air valve is located on the edge, baud straight. Gasoline faucet located in the middle of the baud flowers. Standard factory air valve is opened 1 1 / 2 rounds, I open up to 2 1 / 2 rounds. Then turn the faucet to right flowers to stationary frequency is very low (almost dead).
Setting the two valves is indeed puzzling, why? make low-frequency stationary means enlarging the flow of gasoline. It should not be more extravagant. However, to minimize the faucet instead raise the frequency of stationary gasoline.Raising the mean stationary combustion occurs more frequently, resulting in even more wasteful of fuel. Well Suppose that:Total fuel parched = BThe volume of each fuel burned intake = VFrequency of burning = FSuppose at 1:25 consumption value of variables is as follows:B (0) = V (0) x F (0)The assumption V (0) = 50, and F (0) = 2 then B (0) = 100.Then tap / gasoline baud played out (left, counter clockwise) the means to enrich gasoline or increase as much as 10% V (V (1) = 60) so that the stationary frequency is reduced by half to 1 (F (1) = 1). Then B (1) = V (1) x F (1) = 60 x 1 = 60. Well  even be saving 40%!.Indeed, the experimental results while this seems to result in efficient use of 1:35 or 30%.Actually, gasoline consumption is not only influenced by both the faucets are but by the following:1. pilot circuit2. throttle valve3. needle jet and jet needle4. main jet5. choke circuitEach section accounts for fuel with the following composition:Aperture Gas ---- Part Contributors0 - 1 / 16 ----- 1.

Vespa made ​​chopper

Vespa motor is a motor made in Italy and two-wheeled vehicle has a unique body shape, so make vespa very popular with many people both from the old to teenagers. In Indonesia alone, the Vespa has been a community that very much. Community Vespa motorcycle lovers are scattered in various cities in Indonesia, many also touring activities undertaken by the community of Vespa.
Unique form sometimes makes Vespa motor hands modifier want to make changes on their Vespa. In early 2000, there was a trend to change the standard form of the Italian vehicle is a Vespa chopper. Modifications made Vespa chopper chopper bike because you want to look but with a little budget. In classification, modification Vespa chopper divided into two. First, the modification only to the Vespa motor body without changing the engine. Second, modification of the total change is also part of the machine.
In the hands of extreme flow modifier, they are not half-hearted in changing the look of the Vespa motor. Display the standard Vespa motor can be transformed to resemble the look of the car. Modifications vespa so this car is very complicated to do, because they have to calculate the dimensions of a form that will be generated. At Vespa modifications so the car has a few streams. The first stream is the flow of Vespa modifications to the Jeep. This flow makes the Vespa look like a dashing Jeep while driving. The second stream is the flow modification to sport cars. This flow change nuanced Vespa like a sporty car.
There are several modifiers that choose not to change the body of the Vespa's unique and they choose to tamper with the machine. Modifications made to make the Vespa engine faster. There are also in the modification of these machines exist that alter the working principle of the Vespa motor.
The first Vespa motor using the combustion system 2 not converted into 4-stroke combustion system. However, the development of this modification is intended to drag race. Vespa Modification drag race engine components that have very much. Use of the modified engine components Vespa drag race to make the modification is very difficult.
All decisions ultimately depends on the owner of the Vespa motor. This is due to the owner of the Vespa motor is a person who has the authority to modify the start of the modification chopper Vespa, Vespa modification so cars, and modifications to the Vespa drag race.

How to take care Vespa

Vespa is identical with the spark plug. This is due to two-wheeler Vespa is the most frequent change spark plugs. But if the Vespa we can not mutually exchange plug contrived? The answer could be. Spark plugs are long-lived (morbidly mutually) is not difficult. prerequisite is the painstaking care of the vehicle user. In the language of a mechanic shop "plug NO DEAD". Is it true those words? Below is a small research experience has shown, that the spark plugs Vespa motor necessary substitute for the ill, have a long life. Spark plug consists of two points of positive current (+) and negative current (-). Two points if associated with the setting of platinum / CDI will / sparks. This fire will burn gasoline that has been atomized by the carburetor. between the two points (middle) will be covered by an insulator. Like spark plugs in said OFF and must be replaced if the insulator layer is covered by a crust / soot in the combustion chamber engine block. Why is there a crust? the answer is on the quality of fuel and lubrication oil contained in the Vespa. remember Vespa 2-stroke vehicles, which burn gasoline contain so much oil.

Fuel (gasoline) with quality (octane) Low will leave a lot of soot in combustion components. If possible, vehicles should use high octane gasoline Pertamax like Pertamina or Shell super output. Likewise, the oil side, a lot of leaving the crust / soot if the side with a quality oil (additives) is low. And given the market many many brands of oil supply side, to the owners of vehicles scooters have an understanding of how to choose a good oil. Do not forget a lot of oil is also an outstanding addition to false.To overcome accumulation soot / crust on the spark plug (insulator) that you want can be done to clean it regularly. Open up the spark plugs of the cylinder cop. Clean using a brush with kerosene / diesel / gasoline. or it could be cleaned with a brush using an iron.Brush and brush are only able to clean the insulators are visible, how to part of the invisible?. Use 3-5 strands of steel wire rope clutch that had not been used. Fill the hole insulator with gasoline, lighters and hold the spark plug insulator that has no crust, having seen dirty, pour, and then filled again and the match several times. Do not forget the insulator holes in the condition they will be submerged by a kerosene / gasoline / diesel, so that the crust of the racing engines wire can be removed.Once clean replace the spark plugs right in the holder within cylinder cop. Remember when the spark plugs MUST be cleaned after the cold conditions. Never wash in hot conditions when the spark plugs (new cylinder cop who was removed from heat), because that is the cause of the short life of spark plugs.Remember how the above manuals must be with patience.There is also a manual method is more rapid in cleaning soot / crust in hole spark plug insulator. A quick way is of course the risk is large enough, by using battery water (water zuur) as well as mercury. The trick to do a few steps as follows:1. Pour a few drops of water into the hole battery spark plug insulator, allow a few seconds, then pour2. After being drained quite discard crust, do the washing by using a brush (Brush) soap soap and water.The model in this way only a few seconds immediately clean up the crust. But then again not too long, because if long, the layer of iron / metal that has no insulator layer zuur be eroded by water. if a layer of an advanced eroded the spark plugs will be too thin.Risks due to wear zuur water / mercury are also present, ie if the fumes inhaled our noses would be dangerous. Hm ... .. the risk is quite heavy. Heavy metals will enter our respiratory cavity. How to overcome that is not inhaled by wearing masks.Just you know, if there are people who sell spark plugs with no clothes, still clean, but low prices, please be careful, usually the result of the practice of this model. The result was amazing. After the crust removed, then scrubbed with a brush and soap, it is guaranteed dirt and grease oil will be wasted, plug so shiny like out of the factory.In addition to the manuals above there is another way to clean the crust is by using carburettor cleaner. But if the carburettor cleaner is usually no effect on the spark plugs, because when the liquid in the spray carburettor cleaner, spark plug temperature becomes too cold.If the spark plugs cleaned regularly (3, 4, or 5 days), and do not wait until the Vespa strike, guaranteed to spark ill will never die.The things that cause the plugs to die1. The electricity generated is too small spool2. Coil is too weak3. Platinum / CDI weak4. The low quality of Gasoline5. The low quality of the oil sideSo let's clean up continues, if there is an interruption of the five things above, usually accelerate the destruction of the spark plug. Because it still controls the fifth condition, or if you check regularly confused by the garage / mechanic.NEVER DISPOSING plug

If we were forced to change spark plugs should never be discarded, because the spark plugs are used and stored longer .... then used again, it is usually pretty good ignition.Having not worn spark plugs with kerosene wash and store. day after tomorrow or even next year is needed, god willing, can be usedplug TO MAINTAIN durableThe easiest road to maintain the spark plug is to maintain or improve the quality of fuel (gasoline) that enter the combustion chamber (engine block). The second step is to maintain quality of the carburetor, because the better the carburetor, the better the quality of combustion.Another step is a step quite eccentric, aka no Standard Operating Plant (SOP) of the plant it is to boil the spark plug. The last step is quite telling. yes at least not by the secretary tight dollars, like the child learner.Step SOP without this factory are as follows:1. collect some old spark plugs, new spark plugs or can be purchased. 2. prepare a pot of boiling water in pot on stove as much as half. 3. after starting the heat (turbulent), the input plugs into the pot, allow some time until the water runs out before. Remember do not add cold water, because the temperature will change the spark plugs.So how to boil it looks like people want to boil diamond. Do not let water run out, and do not always remove the spark plug if water boiling in the pot is still a lot. if standardized time is to boil for 10 minutes, 15 minutes, 20 minutes and so on.The longer the boil, the longer it will spark heated, then the resulting quality of the spark plug, the better.Would be great if bought new spark plugs are also treated equally. Experience of my family in Tegal. new spark plugs used vespa through the process of boiling, 5 years  never replace the spark plugs.Once again, remember the adage NEVER DISPOSING plug

Caring batterybattery for the era now a vital thing for motor vehicles, including the Vespa.  need care because every time the machine is turned on, the batteries will have left an electric current.When an electric current into the battery, then the elements in the batteries will react. Reaction of the batteries has resulted in (1) temperature and then heated to evaporate the water battery, (2) heads in particular batteries positive (+) will be no clumping and usually causes rust.Because it continues to control and water content of batteries, at least once a month. Likewise battery head should be cleaned frequently with a brush that has been soaked in hot water use.If the batteries regularly treated durable and continue to be used. And do not forget, if we are old scooter ... .... not used better battery released. Castings / remove the batteries and store water in dry conditions and reversed. It means that there are holes under the battery. When about to be used, water recharge and water battery acid, such as new batteries.The above treatment only for liquid batteries, while for dry batteries do not apply. How to care for dry batteries?Dry batteries do not need water treatments battery checks, but because he was no water in it maintenance free. Just need to remember, dry batteries have enemies, namely the head of water splashed by battery (its main + nutmeg). If nutmeg + water doused the electricity produced is usually not optimal. The second enemy is the occurrence of batteries short circuit between the axis axis + -. because it's usually if we use dry batteries, all batteries closed head plastic coating.

carburetor VESPA sport

HOW TO WORK MACHINE VESPA The basic principle of the machine's performance is based on two-stroke Vespa or two steps, first step is to rinse and its mixture between the fuel and air that have previously been on the set of the carburetor, then the second step of the process presses the fuel combustion chamber so that there was an explosion of sparks plugs and fuels that result .... the impulse piston is rotating crankshaft and gear clutch transmission. Below I will explain the super vespa engine comprising:




I. Carburettor

Carburetor is a composition tool that regulate the supply of fuel into the combustion chamber, this is a tool that works kinetically without electronic suspension only regulate the air supply through the gas lever and steering the handlebar yan no other devices from the carburetor to adjust by itself.
II. IgnitionThe so-called ignition process is the occurrence of a spark plug as an ignition fuel that has been mixed and rinsed by the crankshaft or crankshaft is in the combustion to an explosion that produces a boost piston. Fire in generated of spool platinum spark plugs are in a magnetic field, the stun of the spool in a 2 farad capacitor stabilize ago in signal or system pulsars by platinum stun through the above process be strengthened or larger by coil, this process impact sparks in plug magnitude more than 4000 amperes voltage with a weak point.
III. FUEL ROOM Combustion chamber is a space that is in the Vespa engine to generate power capacity of 150 CC, there is even a Vespa engine with a capacity of 200 CC, here there is a process ization MICTUR or mixing between the fuel manifold of gasoline with air crankshaft or crankshaft after the fuel is mixed material in transfer by a piston which was driven by the previous process been through a transfer existing cavities on the BLOCK CYLINDER, then having pressure fuel into the vacuum chamber that existed at CYLINDER HEAD explosion occurred here was the result of pressure and spark plugs, residual fuel manifold carbon dioxide discharged into the exhaust air out through the hole leading to exhaust that serves as a flue gas compression utilize forth to refine the process further, and also serves as an exhaust silencer explosion,
IV. ROTATION ROUND OR MACHINE Three of the above process produces rotation or rotation of the engine and gear-gear that is in gearbox in through the functioning clutch Clutch or as an automatic neutralizer round gear riders within their desires in overdrive Boxes consists of GEAR PRIMARY or more in the know with the rotation of the gear teeth Borobudur is directly related to the GEAR SECONDARY or better known as incisors. Setting of transmission speed gear 1 to 4 by CRASH GEAR or dental cross these settings directly in his relation to the control or motorcycle handlebars, this machine is unique in not using the power to transfer chain system. In the treatment is cheaper and easily the most important is the accuracy and ignition kit using this machine.
PROBLEMS THAT OFTEN HAPPENS investigated;
i. Carburetors are often dirty or clogged spuyer In this issue directly affects the rate of the motor, the drive motor or motors halting even sometimes difficult to livealso plugs often die from the tip of the spark plug looks black insulation missing resulted in seizures that his spark plugs fire at The Solution:1. Clean the fuel tank from dirt and rust2. Check the fuel hose from the fuel crust3. Clean the carburetor using the air compressor back check spuyer holes do not there is fecal matter, accuracy in demand in this4. Check the hole size is just right spuyer yet not to the greatness or smallness. If greatness is wasted motor fuel and spark plugs are also often die. Spuyer hole size based on the size of the factory default5. Setting or adjustment of needle should ideally fit in my experience do with stationary set carburetor on top suits, and then turn the needle is ideal to use a screwdriver to right after loosen the stop round the needle back to left slowly until you hear the engine on lap too high,
ii. Ignition Problems in ignition also will have a direct impact on the rate of the motor or the motor can not live, difficult ignition starter motors are usually constraints on platinum suits that are not true, it could be one of the ignition device such as spark plugs, coil, platinum, condenser, ignition spool there are already improper use or dead. resolution:

The first step check the color of the tip spark plugs, spark plug tin when black will not fire the solution sets spuyer spark resize the main jet pilot jet dams, beila brick red color of the spark plug tip check to the other ignition parts. Coil is feasible if we not short-circuit spark plug wires by the distance to the mass of approximately 8 mm machine is still going blue flames leap, blue when no color here spark or flame is red it means suits platinum is incorrect or the coil which is already weak , flames leap from the coil directly influenced by the suits platinum, platinum settings are correct within the rift between the connector and the connector plus minus its approximately 0.5 mm. min by using a screwdriver, do not need to remember tuning in because it will shorten revealed lifespan because between platinum plug is not straight or crooked. Jump that occurs in platinum also Examination of conditions related to the condenser condenser is very easy what happens when jump fire in platinum condenser is in because you are not worth taking, replace your condenser or any other means of graft condenser with other condenser or on double its condenser system with the same size condenser capacity 2 farad, The latter is a spool check your ignition is still suitable to be used or should be in a new with fire, a sign of faulty ignition spool, coil spool usually blisters, loose spool reels, spool end.If everything is stable, then you must check the accuracy nap or ignition but before see first magnetic spi condition broken or not also see the condition of the rotor is still good or not, the size nap before the point is 21 degrees off axis or conditions on the piston head.
iii. Jammed starter motor can not trouble This is a machine that is more fatal usually this happens in because BEARING ball bearing or are damaged, handlebar ball bearing or connecting Rood damaged, broken ring ball bearing, or PISTON not worth taking, boxs gear device in there that broken, PRIMARY TEETH PER loss, CLUTCH PLATE which is not worth taking.
