Carburetor Setup

(1/1)

bpruiett666:
I just bored my 2001 kx125 sleeve from a 54mm to a 56mm and I am using a wiseco prolite piston.  I am at about 100-200 above sea level.  Do I need to make any adjustments to my carb, such as jetting?  Or will the jetting I had before be close enough?

Coop:
My money is you will find the pilot is ok but that you are a little running rich on the main now. Just sharing my experiences jetting big bores.
