Wanted XJ650 Maxim Engine ~1981

Hey Folks,

As you may know I've been working on this bike for a long time but recently had an issue that was beyond my expertise and time so I took it into trusted mechanic who identified a top end gasket issue.

During the tear down here we unfortunately found several other issues, some very bad wear between the cams and head some internal wear on the cylinders ( no hashing left ) and some piston play in the bottom end. All said and done it's going cost way too much here to fix these things so I'm looking to do an engine swap out.

If anyone has a rebuilt or known good engine that would work, preferably in Texas let me know. I'll consider anything but a midnight maxim from any year that would mechanically work in this bike would be ideal.

 

That's a tough one - I think even a "known good" engine would come with question marks, and one that has been properly refreshed is going to be expensive.

I have a spare non-YICS Maxim engine, but who knows what it looks like inside. But if you tear into it to verify condition and refresh it correctly, you're going to spend some good money just on parts (gaskets, o-rings, main chain guide, starter clutch parts, etc.), and then if you have to pay labor to do it, it could get expensive fast.

Hopefully somebody has something that fits the bill - but my advice is buyer beware.

Unfortunately, this is why this is mostly a DIY type of project for most of us.
