Re: Building another FZ17
On the smaller bikes (400/600) the '08+ R6 shock is a very simple but not quite direct swap. I'm wondering if the R1 or something would be a swap to the YZF

Re: Building another FZ17
I've obtained a YZF750 frame for this project. I'm wondering if anyone knows if the actual shock length is the same from the 1K to the YZF? I have an early Ohkins from a 1K that would make a decent start point for the build, but with nothing to compare to I'm not sure it will work. I know there's an...

I'm headed out for our last race of the year with our FZ17, and I'm picking up a YZF750 motor for this winter's race project. I was recently reading some threads on "poor-man's OW-01" and am doing some planning. I have a 91 FZR1000 donor motor that I'm thinking of robbing the head off of and swappin...
