    Anyone seen cam chain destruction like this?

    Appreciate the replies. I’ll put some work into the engine and give it a fair shake, see how it’ll run.

    Afternoon everyone I recently finished a ground up cafe build on a 1975 CB550F. It’s been running like a top and pulls like a small train. I’ve ridden about 150 miles since I finished the build and I’m extremely pleased with the way the bike has been performing, until last night. Details...
