I have a 98 900RR Frame with a Rc51 Trees.. the top Bearing
doesn't fit into the frame, But the Bottom does?? the Fork stops
also don't stop it untill the Forks would hit the Frame..
Guess I Need to get the 929 Trees...






Heres the Build Going so Far..

 

I just put an R1 front end on my F4i, and I had to get a custom sealed top bearing to make that work, also. I'm sure its gotta be a different size, but if you mic the inner diameter of the frame and the outer diameter of the stem, you should be able to find a sealed bearing for your application for about $15, pretty easy.

Good luck, bro!!

You've been w/out a bike for tooooooo long!!

Frame looks SICKKKK!!!

 

I know the place to call... thanks homie..

 

I would just get new upper and lower bearings. Go to a bearing wharehouse they can come up with something for sure
