I bought a very rough 77 550K recently. I pulled the carbs apart today to see what's what before I order kits. Number 1 carb's float bowl has no overflow tube, it's been broken off and discarded. I don't imagine it would be worthwhile to JB Weld a new tube in place.. If anyone has a float bowl in good condition available please PM me.
I am also looking for a lot of stuff for a very incomplete 74 CB350F - carbs, airbox, wiring harness, front and rear wheels (with brakes & axles) and front forks. Again, please PM me.
