Hi everyone- I am a new motorcycle owner and motorcyclist in general. I just bought a 1971 CL350. She runs but needs some work. I purchased a Clymer manuel and am waiting for it to arrive so I can start getting my bike street ready. The exhaust pipes are not original- she seems to run a bit rich and is backfiring like crazy. The key is stuck in the ignition since I bought it and I can't for the life of me get it out. Ive tried WD-40, graphite powder and just tugging it a whole lot. Im excited to start learning motorcycle mechanics and to start riding.
