    Sold / Found / Inactive - 1970 yamaha XS1

    That sounds similar to my experience when I sold my carefully restored 1970 XS-650. I always wanted one and satisfied that need quite well with the resto and a few rides. I was strung along for a month and a half by a chap from Australia and I finally dropped that and entertained a visitor from...

    Comment by 'Scooterbrain' in media 'XS1'

    Wow. Just tha way to buy em. Pukin their guts out of the headlight hahaha. I wish mine had been that complete when I bought it . I sold mine a few months back and actually came out ahead. I would sure be tempted by another XS1. It was really a lot of fun sorting out the tranny and sourcing all...

    OK so here is the result. Rode it a mile today and has no missed shifts. Got 5 gears. Did not slip out of gear. Once was a bit hard to find neutral. Rear chain still a bit tight as is the tranny. didnt ride too far as I still have a bit of sorting to do. On reassembly I managed to get my...

    Yep. Glad You agree. Two passes on the gear and it was still a bit tight, but dressing down the shaft a tad did the trick. I will re-clean and polish a bit too for good measure. Tomorrow evening and Saturday I will re-assemble and triple-check everything along the way. Oh by the way Yes when...

    So in additional summary, the one without the rebated splines, be it right or wrong, is what I received the bike with and the one that you would expect would Bind on the shaft but that's not the case. It is however the one that was installed when the bike fails to shift.

    Ok I have Mis-described something but here is the deal. The gear in the "Foreground" that you marked ??? is the one with the taper on the splines is what was installed on the bike when I bought it. It slides smoothly even when jammed up against the stop it does not bind. The Gear in the...

    Three pics added. So, My shims are not here yet, maybe tomorrow. See compared Old Fourth gear slider against the new and see how the new gear does not have the splines cut down where the gear back-seats against the shaft when first gear is Dis-Engaged. It binds horribly of course. I thought...

    Jeeze, AMEN to that.... That New 4th gear was tight as hell. With a little dressing off and Oil it moves pretty good now but I am going to massage it a bit more. I feel really good about getting the slop from .052 down to .013 and with New Gears too I feel even better. I will smooth and polish...

    WOW 2M. awesome specs. And I know that was some work.They USPS mailed my new first gear this morning about 10 so I am thinking that it will be here when I get home from work Wednesday. and Yeah I knew there was no way that .054 was anywhere near acceptable. Your spec "0.003"-0.005" for a free...

    Hea Thanks again. Research is so much fun. We sure as hell don't do this to make money. Anyway I do have the correct Shaft and my old 4th gear has no notches cut into the gear so that's orig. The polishing on the splines looks a bit crappy/rough but the old gear slides real slick on it. The New...

    Might be a littler easier than I thought to find a good used one. I see now that the 1970 number for the fork is the same as the 75, 76 and even the 1981 so that,s a relief. there are plenty used ones out there that look pretty good in sets.
