I just purchased this 1973 Yamaha RD350 a few days ago for $750. It's not running, and it needs a lot of work, e.g. carbs, points, gas tank, brakes, rust, greasy mess. This is my first motorcycle so, I figured I would go all out. I downloaded the original manual for it online but it didn't explain how to remove the carbs for cleaning. I tried for a while earlier but I don't have an allen wrench that can fit between all of the hoses and tight corners. I tried just loosening the clamps at the y-boot and on the other side but there wasn't enough play to remove it. Am I doing this wrong?
