Guys,
HELP. 2008 YZ 125. Sounds crisp until you hold it wide then it breaks up. I rebuilt carb with stock jets. Bike is stock. Put in new crank seals, new top end. TILL happening. Carb has all new float, jets, seat etc.. Measured fuel level. My gut tells me MAYBE reed or coil??? Coil ohm to spec. PLEASE any help would be appreciated.
Old piston looked good. Idling high even with throttle cable out.
Thanks
