I have a new SU-5589 Air filter and Buddha jet kit with 132.5 mains, 20 pilots. I had a 2001 GS with a stock exhaust. I pinged Buddha before ordering the jet kit and the 132.5 / 20 with stock mid-mains was what he recommended. I paid $54 for the filter and $25 for the rejetting kit. I would like to sell them together for $60. Anyone interested?
Restrictor has to be in on a 04+ and 01/02 dont need it. So it should work on all 01+ bikes with that.
Cool.
Buddha.
