Hey guys new to the forum.
I’ve got a 2004 cr250r that’s in beautiful shape. However, it will not idle. I’ve cleaned the hell out of every orphace in the carb, and have cleaned and recleaned the idle circuit. I set all jetting back to stock.
Symptoms:
-When warming the bike up it loads up bad and and the only way to clean it out is holding it wfo for 5 or 6 seconds.
- the air screw has no effect on idle speed, I can run it all the way in or completely remove it with no effect.
-Also there seems to be a lot of unburnt fuel getting kicked back into the air box. (From the reeds) but this happens with the stock reed block installed or aftermarket vforce 3.
This thing is giving me one hell of a headache. Any ideas or advice is greatly appreciated.

An easy way to check the mag side crank seal is to get the bike running and squirt some carb cleaner behind the flywheel. The idea is to see if the revs climb because the crankcase is pulling in the carb cleaner. I've also heard of people using an unlit propane torch with the fuel on instead of carb cleaner
