OK...I had to rejet my bike....even before I put the pipe on...it did not run that well...It is typical that most KX250F's are to rich on the top and to lean on the bottom....Put the PC muffler on the bike and see what happens.....About eveybody on the KX250F forum here at TT has had to go larger on the pilot jet.....

jetting would be very close pc pipe or stock. but the kaw jetting stock needs to be fixed here on the east coast. i run 42 pilot in summer 45 till it gets hot. ncys or ncyr needle. 175 - 180 main . put those jets in and see what a difference it makes i would even ride mine without jetting it first.
