Carb Newbie...

Recommended Posts

hey when i bought my bike the guy messed with a white plastic knob under the carb and small screw facing the shifter side of the motor on the very bottom of the bowl. I (obviously) know nothing about adjusting the carb but my idle is a little too fast. I tried turning the white plastic knob but it doesnt want to turn. Question is is that white knob the idle adjustment or am i not messing with the right thing... sorry for the probably obvious question but i cant quite find what im looking for using search:confused:

I hope you get your answer- I am dealing with lean running popping on deceleration and I turned that knob on the carb and it has improved my lean situation greatly but didn't really raise idle like I thought it would.

white nob will not fix a lean condition, has nothing to do with mixture..it adjusts the throttle resting position.. it should turn, clockwise to idle up, counter clock wise to idle down.

+1 :thumbsup: Also adjust it when the motor is warmed up.

it should turn with only a little resistence,,unless yours is seized, rusty,old 01 probably,etc..might want to try some wd40 or the like with the extension tube thingy, and spray it from the other side, give it a light tap...
