Does anybody know if a top end going bad will cause a bike to not wanna idle when warm? Ive got a yz250 and it will idle fine while the engine is cold but as soon as it comes to temp it will die out. Ive got the idle control turned as far in as it will go and the bike still wont idle. Any help would be greatly appreciated. Thanks
There are 2 screws on the left side to adjust the carb. The top one is the slide stop, and the bottom one is the air screw. No idle adjustment, per say? If you have spun the top one all the way in, and can not achieve an acceptable idle, the slide/ slide stop screw may be worn out.
