I have a 2000 XCR 800 that I am rebuilding the motor on. Crank and rods are fine just freshing it up a bit with new bearings and seals. Did a quickie top end last year but want to be thourough as I have a little time off. When I pulled the flywheel found a chip and I want to replace it. I can get a flywheel from a 96 ultra or xcr 700 on the cheap that I have heard will work. 98 ultras have the same part number. Has anyone tried this I've read in older racing forums that they used them to try and get more power just have to play with the timing a bit. I guess I'm looking for suggestions as I want to get out soon tired of the wifes sled. Otherwise I found a few salvage flywheels for about $200.00 and new they are $317. Suggestions? Thanks for any replies.
