I have two XB12 motors with issues, one has a bad left case, the other has damage to the right half. Is it possible to mix the to good half's together, and if so is there anything to watch out for? | ||

bearings in cases must be line board together to keep every thing straight and true. | ||

The cases are sold as a set; so the answer is no. | ||

Maybe you can compare the case halves with each other and check how much difference there really is! | ||

You have the same problem with cam caps in UJM's. The head itself is the bearing surface for the cams, with cam caps bolted down. The heads and the caps are machined together. Hypothetically though, suppose somebody burned up a KLR-250 head embarrassing squids on Deals Gap (it's all great fun till the smoke starts pouring out). Then say they found a perfect head on ebay, but it was missing one cap, a cap that wasn't hurt in the initial failure. Say somebody took that head, put on the cap they had, lapped it in with a little valve grinding compound, cleaned it really well, and bolted it back together? It might, hypothetically, work just fine.  Crankcases on a long stroke air cooled twin are taking that to a *whole* nother level though. I'm sure mixing cases is a bad idea. I'm not so sure, especially given modern machining and processes, it wouldn't work though. | ||

I think I will play it safe and get both motors repaired correctly. Who can you recommend in the southern California area that can do welding repairs on the one set of cases and I also need the inner cam bushings replaced and pinned on the other motor. | ||

Al at American Sport Bike should be able to direct you to someone if he can't do the repairs. | ||

Isn't there a rolling bearing mod for the cams? That seems like a better option if you need the cases machined for a bushing. |
