Keihin Flat Slides

[JohnnyTheCraneGuy]

Does anyone have any recommendations with Keihins? I'm looking at acquiring a pair that I could use when I swap to the bigger pistons and maybe cams. Another reason too is I'vw seen them come up on facebook here and there for a Y\FZR750, a kehins FCR39. But from what FJ1289 was telling me, those are set up for downdraft rather than side. Another was listed as a CR31-3051 for hondas CBFs, I messaged the owner and he said they were down draft as well, so I am scratching my head a little bit here.

If anyone has experience with this and could share the specific models I would need, that would be a huge help for me.

Johnny,

Can't help with specifics, but I would send Keihin an email direct, and see what they advise.  Website:

77-85-77 is the carb spacing you want to fit our FJ's.

The Mikuni TMR36 or 38's roller flat slides have a choke for cold starts

The more expensive Keihin FCR39 roller flat slides do not have a choke.
