beamish owners club Posted December 21, 2011 Report Share Posted December 21, 2011 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? Link to comment Share on other sites More sharing options...
rhinouk Posted December 22, 2011 Report Share Posted December 22, 2011 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 Link to comment Share on other sites More sharing options...
suzuki250 Posted December 22, 2011 Report Share Posted December 22, 2011 Is the OKO just a copy of the Keihin PWK ? Link to comment Share on other sites More sharing options...
