The casting on the engine case of my '76 CB500T that stops the kick arm on its return swing has broken off, so the kicker is now free to rotate too far forward and the mounting bolt for the kicker arm has punched a hole in the side cover. Theoretically I could build it up with some welding rod, but that would require a lot of disassembly of the engine to get to it that I'd rather avoid. Has anyone ever seen this before? It broke off to perfectly match the arc of the tooth on the jackshaft that is supposed to hit the stop, so I'm wondering if this is a common weak spot. Is it possible to drill into the case and insert a dowel or something to catch the jackshaft?
