What's the shaft for Jimson?
When I did my XT500's I found the shaft from Yamaha YZ/IT triples was was too short and Suzuki too long. I used Suzuki shafts and shortened them. I ran the bearing surface further down, chased the thread a bit longer cut the weld holding the nut in place, shortened the end of the shaft and rewelded the nut.
Easier than it sounds!

PS Yamaha and Suzuki shafts interchange on YZ, IT, PE & RM. Honda are different
