December 21, 201114 yr Has anyone replaced their Mikuni VM28 with a Keihin PWK28 or an OKO flat slide carb? How does it work on the bike and what jetting did you use?
December 22, 201114 yr I put a keihin PWK28 on my 325 Bultaco off of a 250 gas gas pilot jet 45 main 128 and it tranformed the bike.would have thought the jetting would be about the same for the susuki
December 22, 201114 yr Is the OKO just a copy of the Keihin PWK ? yes Some say a poor copy but i have never tried one myself
December 23, 201114 yr Author Thanks for the information Rhinouk. I have an OKO carb on my TY175 and it works really well.
