Hi Johnny, Im AL the owner of Big As Auto Repair.

Johnny, here's something I want you to try. I want you to start the engine while giving it a little gas, not much, just enough to see if it will idle. If it does Idle and stays running with your foot on the gas and dies when you remove your foot. Then go and buy an 'IDLE AIR CONTROL MOTOR" It mounts on the throttle body. Put that on, there are only two screws that holds it on, very easy to replace. After installing it the idle will be real high, this is normal, just wait it will stabilize and idle normal. NOTE: if it still dies even with your foot on the gas, then you have another issue but this is a good place to start. Hope this helps and please visit my auto-repair-website at: http://www.bigasautorepair.com/

Is this engine equipped with an EGR valve? Might have carbon deposits blocking the passageway causing the stalling problem.

Sometimes that's caused by a vacuum leak near the manifold area.

Sometimes air in the coolant will cause an idle problem. Air will keep the air temp sensor from sending proper info.
Hope this helps.

check your valve clearing, and clean ur carberator if you have one. Otherwise it may be electrical or fuel injectors are going bad

Replace idle jet with a new one OEM is $5.00. If won't idle still the compression is so low that it won't stay running Or possibly the main seals are leaking (a 2 stroke has top end & bottom end compression.)

check to see if the choke is stuck or the carb could be dirty (gummed up)

Sounds like a loose piece of crud in the main jet. Have you had the jet and tube above it out? It could also be a spark problem. See if you have spark when it tries to die ( put a nail in the plug boot and get it sparking 1/4" or so to the plug at idle then rev it up, it should continue jumping. I think that bike will also have mechanical spark advance on the rotor on the end of the cam. If the springs are loose on that the spark timing will be all over the map and can make it run intermittantly.

Sounds like it's getting air between the carby and the motor. Check the intake manifold is not leaking
