I just picked up both a 1990 GSXR1100 and a 1992 GSXR1100. 1990 Stock but with California needles and air jet. 1992 Yoshimura full exhaust with stock jets and California needles and air jet. Question....... I am changing both the air jet to the 1.35 non California jets, and the needles to the 0-8 non califorina on both bikes .... Should I just leave the stock jetting or incease in for the Yosh pipe? Or do you recommend dynojet stage 1? Factory pro? Thanks. Tim
