I'm wondering if anyone knows a good source for a slipper clutch conversion for my 2000 F4. I have this on my VFR400 and my RVF400 which both came that way from the factory. I miss that feature on my F4.

 

It is not made for that model, I tryed to find one, a couple of years ago, for a friend. And no luck.

 

I'm not sure if or how similar the clutch basket is on the F4 to the F4i - But on the race car we build, we use an 600rr (maybe its made for the F4i, but I am pretty sure its an RR one, if not the plates/disks come from the RR) slipper on our F4i engine. The main issue was height of the slipper interfering with the cover. So we machined down and old cover and mated the two flanges together to shim it out from the block and buy us some more space. If you are really interested in doing that, I can try and get some more details for you. We used to run and F4 engine 5 or 6 years ago, so I might be able to ask some of the old team members about it.
