My friend just bought a 1980 XS650 that has been turned into a bobber. Once he got it home and took it on the first ride the shifter fell off. Upon inspection it appears that it was sort of welded on to the shaft somehow as the set screw has been ground down smooth. It wouldn't surprise me if the guy he bought it off of did this to make it look "clean". Inside the shifter it took about a quarter inch of the end of the shaft with it. Looking online it appears that the if you just take the right side cover off you can access the shift shaft and just pull it out and slide a new one in. I did a little forum search but found nothing about this particular job. Does anyone have any experience with this? Thanks in advance.
