View Full Version : Damaged Cam journals - Junk Heads?

12-02-2017, 09:22 PM
Just wondering what you folks think about the wear on these cam journals. Bottom end spun a rod bearing at roughly 2K miles. Im wondering if it lost oil pressure. Either way, engine ran before disassembly. Cam journals have some nasty wear. My local shop doesn't have the tooling to align hone the cam journals on these small motorcycle heads. Guys think these are worth rebuilding? or more trouble than they are worth?347328347329347330347331347332347333

The third picture shows some deep scraps from what my old eyes can see.....you don't have a local race (car) shop in your area?

Local shop is the spot that has done both head and bottom end work on auto engines ive raced in the past. For some reason their cylinder head guy doesnt want anything to do with the bike heads. I mainly wanted them to look at it to see if its viable. If I do decide to go ahead with the heads, they will be sent to a builder in TX.
