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

Is the OKO just a copy of the Keihin PWK ?

Thanks for the information Rhinouk. I have an OKO carb on my TY175 and it works really well.

What size OKO do you have on your TY175? 24mm or 26mm

I have a 24mm OKO on my TY175. I am just having a Mikuni flat slide developed for the RL325 and a 26mm OKO for the RL250 - watch this space!
