need help with bog

[rmuscle]

drr 50 sunworld carb 100 main 38 pilot, bike was running great , now when he starts it up if i dont let it sit and really warm up when he punches the throttle it will bog than cut out. if i start it up and ease into the throttle it seems to load up and then it is fine once warmed up runs fine. would this be to lean on the pilot

thanks

yes, pilot needs to be 40, also drop the needle clip to a richer position , one groove down.

Be sure you mention it is a 21mm Sunworld and not the 16mm version so you get the right advice in the future

Marc is on the money with his advice with the jetting
