Sounds like it is running lean or float level too low,,try a bigger main jet and let us know how that works...

Soory...did mean to laugh above. I'm old and not button saavy. Regarding our fuel, as 190mech stated, the float bowl level, if too low for your wheelie angle will starve your fuel, as it is forced to the back. (The bowl bottom becomes the front wall, the rear tilted back to form a ~45 degree vee angle, so the pickup point becomes vapor.) That can happen even when not trying super bike/stunt bike actions. Hard acceleration with a low float bowl level can make that happen too.  Your English? Looks like you do well. Spelling not so, but I would give much credit for spelling phonetically...just like the word sounds! Cool in my book. I get it. As American living in Thailand I struggle with Thai language. |

There's a few folks over on Moped Army with GPRs and RS50s and such. May find some more specific answers there.
Does your carb still have the little washer doohickey around the jet that is supposed to keep fuel where it belongs? I tossed mine as I was told it can let the engine lean out on extended WOT runs and is only for mx type stuff where the carb winds up at dumb angles. Like doing wheelies.

Sounds rich it's four stroking maybe does it get better if you let off that throttle a hair if so that's your issue

hey thanks for the replays i cahanged the carb to a 16mm dellorto 110 main jet. and now it will do whelles again but my top speed is way down. sow i was thinking that if i jett the 21mm carb down from 150 to somthing smaler that will work. and yes i do have that washer bheind the main jet. and how do i sett flote bowl level? can i just bend the metal conektet to the closing maknisem. and yes it is a 2stroke. 2stroke fore life
