Since I am the owner of a motorcycle Java-350, I can confidently say that this is a motorcycle designer. Very often the motorcycle just refuses to start or is unstable. The reasons for this are many, but some of the most frequent causes can be fixed in the field with a minimal set of tools that should be in the glove compartment of each owner of this motorcycle.
Instruction
Difficulty level: Easy
What you will need:
A set of tools (listed below)
step 1
First, let's start with the tools necessary to troubleshoot basic problems. First I will give a list of tools in my glove compartment, then the MINIMUM required.
In my glove box are: Pliers, screwdriver universal, set of Allen wrenches (Some bolts I replaced hex) wrench Set (6mm-20mm) four spare candles, calipers, spark plug wrench, netfile, a small piece of sandpaper, a nail with a mark of between 2.7 mm (for adjustment of ignition) knife.
For minimal repairs needed: Screwdriver, pliers(in rare cases) spark plug wrench (required) a set of spare candles, sandpaper (if spare no candles and home I want to drive a motorcycle, and not to pricolici) Key 10 (preferably a collar instead of carob, it is more convenient).
2 step
Now let's start parsing problems. Consider two major problems, why not start the motorcycle: First you have is not working properly, the carburetor, the second you incorrectly operates the ignition. Let's start with the ignition.
3 step
The ignition system used for the explosion of fuel in the cylinder, the explosion is initiated by a spark.
Now consider different ways.
If the engine is sneezing at work, or when you try to crank most likely you have incorrectly configured the ignition spark beats either too late or too early.
How to check this?
Remove both plugs.
Unscrew the two bolts on the crankcase cover to the right, remove the crankcase cover, appear to be two systems, on the left of this machine and the clutch on the right is the Ignition.
Check the spark. Put on the spark brodarevo, but the candle is not crucified, and put on the cylinder, so that the metal part of the spark had contact with the cylinder. under the cover of a casing in the center of the generator can be seen bolt on 10mm. worn on the key inserted in the cylinder which checked the nail, screwdriver, netfile or something like that, and twist the key clockwise until the nail will not be at the highest point. This is called top dead center (Hereinafter TDC) of the piston. do otenko on the nail along with the top of the cylinder. Take out a nail, make another mark on the 2.7 mm above the first mark, the more the better, (for this I need the calipers, I drive a nail with marks)Now insert the nail into place, turn on the ignition, twist the key slightly counterclockwise, then twist clockwise. The spark must beat when the piston is at 2.7 mm from TDC. Check both of the cylinder when the spark hits in time, then putting it all back and skip this step, if the spark sooner or later read dalshena generator, around the Central bolt are two contacts when the contact opens the circuit (off the ground) is the spark. First, find which of the contacts to which the cylinder is. Then put the ignition on the desired accuracy, it is necessary to slightly loosen the bolt near the contact, and to move the contact. If we shift the contact from the center of the spark hits later, if earlier. Adjustable and collect.
step 4
The next cause weak spark. Causes a weak spark which you can fix in the field dirty contacts, bad spark, or if you have a spare capacitor can be checked. First, let's check candles. To check for spark remove them, connect to them both buenaposada, and lay them side by side on the cylinder, turn the ignition and turn the engine Try to start carefully looking at the candles. If one spark is weaker or non-existent change candles in places. If no spark on the spark we need to change the candle, or clean it if spark is not present on the same wire, it is necessary to dig deeper. Consider the first case. To clean the candle after that it will serve less, but to the house to get enough. To clean the gap emery paper, and to experiment with the size of the gap, set the gap to achieve the most powerful spark.
The second case, if there is no spark on the wire the only reason that you can fix in the field a bad contact. You pull all the wires, babine (located under the fuel tank and the generator. You may have clogged the contact plug, it is necessary to remove the cover to the right, to make contact, put nazhdachku and clean, generally it is necessary to achieve maximum smoothness and the area of contact of contacts, the better the contact, the stronger spark. The remaining issues can be resolved only with special tools, if anyone is interested in more subtle instruction write, I will be.
5 step
With the ignition sorted out. We now turn to the carburetor. Everything is a little easier, but more interesting (in my opinion, don't like to mess with wires and contacts).
First, imagine that we have the ignition in order, perfectly exposed, and do with it problems can not be.
If the bike still does not start you need to find out the reason. There are several reasons. Look for symptoms. If not start in any way, nor with the included suction or without it, do the following: Remove candle(any, I'm twisting the left) and see what condition it's in, if the candle is completely dry so gas does not come, if the candle is on the contrary very wet so gasoline is too much. Either scanned by another without first unscrewing candles are trying to start removing the gas on full, and without suction, if the motorcycle pours it starts the only way, or pusher, is also turned on full gas. If there you have two options, either continue to suffer in the same way, or to adjust the carburetor. The reason why pours too high up the needle accelerator. Unscrew the top cover of the carburetor (two bolts) take out the whole system which is hanging on the rope, presses the spring to the lid, and take out the needle, the needle wears rectangular washer, and several grooves under her. The lower washer is, the higher accordingly, the needle, the more gasoline goes into the cylinder. Perfect middle position, and if so is the average set top. Collect verifiable. If everything was left just put the needle in place, away from sin, it is not in it. Check the nozzles. Turn the carburetor(Yes, Yes, rotated, it rotates in its socket relative to the cylinder in a horizontal position, waiting until poured gasoline(let poured on the engine, do not worry, there are all provided, will go to the ground). Remove the four screws from the bottom, remove the lid and check whether all the nozzles in place, and until the end whether they are tight. Tighten until the end, gather, get. Go to the occasion when it is not doliwan. To install it remove any candle and poured into the cylinder a little bit of gasoline (About a bottle cap) and try to start, if after these manipulations the bike wound up means respectively Netrivet gasoline. There are several reasons for lowered needle how to fix already know. Or a clogged jet, most jet ejector. Turn the carburetor in a horizontal position, waiting until poured gasoline, remove the four screws from the bottom, remove the cover remove the jets and blown them. All must be clean hole through which will pass light. Then blown through the slot nozzles (Better pump or a powerful compressor) but in the field will go and your own body. Collect lead. The second reason for netrivet the carburetor where it sucks air past vozdushka and accelerator, but in field conditions this problem can only be solved zamazal all sealant, unreliable. A more detailed solution to this problem will describe only at the request of readers, And the third reason is the Insufficient level of the gasoline in the carburetor. In field conditions can be solved if you have a set of keys, and when a sufficient amount of gasoline in the tank. Again, a detailed solution to this problem describe in the instructions with the rest, if they are needed.
6 step
So we covered the basic, the most frequent causes unstable operation of the engine of this motorcycle. If you want a more detailed explanation, please write in comments and in PM, I will try to reply to all, or to write a separate statement on the most frequent problems.
