Hi All ! I recently purchased a 1971 U7E..it worked great for a few months then I started to have problems. The problem is the crankshaft. Its worn out and either has to be rebuilt or replaced. The problem is where I live there really isnt anyone that can really rebuild it properly. My next step would be to find another crankshaft. I dont expect that will be easy either. Any suggestions would be greatly appreciated. Please help me get it back on the road! Cheers!
