OKO or PWK28 flat slide carb on RL325?

11 posts in this topic

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?

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
