I'm planning on getting a Bill Blue modified Mikuni TM33/34 pumper carb for my KLX250 and would appreciate some feedback as to the best duration for the fuel "squirt".
Does "up to 1/3 throttle" seem about the right duration?
Cheers

 

I wired mine to be inoperative, you really don't need it.

 

I set the duration on my 36mm Mikuni for best throttle response. With engine warmed up and in neutral, keep blipping the throttle while adjusting the duration for best response.

Ride on
