Hey guys! It's been a while since I have been on this forum, and it's good to be back. I'm interested in picking up a gasket set for a friend's '76 XS360, and I'm not seeing a lot of options out there. This is pretty much the only one I'm seeing:

Does anyone know if this bike shares parts with any others? I'm having a hell of a time finding rings too... just wondering if maybe some of this stuff is interchangeable with the 400cc model, or any of the other Yamahas. The bike has been siting for a while and I want to go through the motor for him before he tries to fire it up.

Anyone have any experience with these bikes?

Thanks!

Oh! Bonus question for those in the know:

I kicked it over a couple times the other day just for fun... it seems to have reasonable compression (didn't do a test as I plan on pulling it apart anyway) but there is a strange "spinning type of sound that is hard to track down as the kicker returns. It may be coming from within the right side case, but I have not opened it up yet to find out. The sound begins right after I kick all the way through, and it sounds like a loose washer or bearing spinning on a shaft, and lasts for a good couple seconds.

Anyone have any idea what this could be?? I can't say I have heard anything like this before. Come to think of it, there was also a strange "klunk" sound if I put it into a high gear and push the bike. Any thoughts or ideas on either of these issues would be appreciated before I pull it apart.

Thanks guys!
 
As far as I know, the xs400 shares all gaskets with the potential exception of the head gasket.

Currently filling my bathtub to wet sand my 360 forks, mid restoration.

Okay thanks, that's helpful. Do you know anything about the rings? Also, why not fill up a squirt bottle for wetsanding? Do you have a build thread going?

Thanks,

The bathtub has nice warm water and it's 4C outside. Plus it needed cleaning anyway.

No build thread, it's just a barn find that is getting a resto. Nothing special.

The rings, pistons and bore size are all 360 specific.

I saw that this morning after putting some more time into my search, thank you sir. I am however learning that STD rings are pretty much non existent. I guess I'll open it up and hope for the best.

I would still be interested to hear if anyone knows of any rings from other bikes that may fit.

Thanks, guys.
