The engine overheats really easy and fast and then cuts the engine off and takes about 10-15 minutes to cool down before it will start again

Adjust your idle screw on your carb so that it gets more gas just sitting there at idle. Tighten the screw one and a quarter turn and then start the bike. Adjust the idle to where you think it sounds normal. If that doesnt work check your float in your float bowl, it might be stuck in the down position. Clean with some carb cleaner spray and make sure it moves freely before putting the float bowl back on, youll have to choke it or prime the carb again to get it started. All the choke does is let in more gas and oxegen so you might want to check how far the carbs close when you push the choke back in. Is it impeading any normal carb setting. Check that too. Good luck.

Checking the colour of the plug may tell you what the general state of tune if like for the bike, but the sudden stops sure sounds like ignition system failing. Fuel delivery still there, although it may well be flooding/overfueling for some reason when the problem occurs. I suppose you have checked the VIN (RM021000000000301 to RM021000000008715) just to be sure that your bike if not one of those affected by the recall. I would be asking the Yamagents to check for the mods/recall to be sure that whatever the solution is has actually been done to yours. The reference to wet weather would be inclining me to follow that up to the max. Sounds too close to the problem to not be it.

Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? Drain a cup of gas from the tank. Any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).
Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.
Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the two screws on the outside throat of the carb and spray into the screw holes as well.

Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. Set the idle speed with the idle screw. This process should get you back on the road.
Since you mentioned uneven idle revs, be sure the carb and manifold are on tight and also tighten the cylinder and head. Air leaks can screw up the idle.
Please rate this solution. Thanks speedfreak41

MAN ITS A MINOR PROB JST CHANGE THE SPEED OF COMBUSTION IT SHOULD BE 1 MIN AT UR RPM METER IN THE BIKE AND ITS PIN IS NEAR THE CARBURATER JST CHANGE IT AND ENJOY UR RIDE
