ive been trying to figure out why my bike is running rich and i was wondering if i changed my fuel oil ratio if that would help ive been mixing it 32 to 1 like the factory says and i was also wondering if maybe some how clutch oil is getting into my cylinder and fouling my plugs if so how can i tell and what do i look for
first try your jetting, but i've had the same problem and i've lowered my jets by 20 with no improvement, and now it seems like it may be a crank seal.
does it smoke EXCESSIVLY ?? does your trans oil go down ?
if your trans oil DOESNT CHANGE level then try the 32:1-40:1 fuel mix
if your trans oil DOES CHANGE then you have a bad crank seal and will need to tear it down and put in new seals
