Question about Motorcycles
Popping when you let off the throttle is a sign of running lean. Could be caused from leak in intake boot, air/fuel screw on carb adjusted incorrectly, wrong pilot jet, dirty carb. When I say lean I mean lean as in too much air or not enough fuel on the low rpm side.

I have a crf 250 R and i have learned multiple things about these bikes like if you leave it running and not riding it for about ten min. it will over heat. they love race gas 113 octane,and alot more. but your prob sounds strange. i know if you hold the hot start while its runing it pops that could be a problem. or it could be you are not cleaning the bike out i would need to know more about this to give a definate answer but try going over the bike. Look at key parts like the
any thing that is nesessary for the bike to run.

Pull the slide out of the throat of the carb then move the clip at the top of the needle down one notch, two if needed. This will richen the low end fuel mix.
Need a "very helpful" rating asap. Thanks!

The choke should only be used when starting cold. After the bike is warmed up you can turn the choke off. If it keeps shutting off after being warmed up for a few minutes, then check your gas/air ratio for the idle air mixture knob. Loosen it up 1/4 turn to allow more gas to flow.

Take your carburetor apart and clean it. Paying close attention to the slow jet and slow jet passageway through the carb.
