Honda CT90 Engine Reassembly

When I was younger I always liked CT90's, but never owned one and started to think it would be nice to have a CT90 up at our second home up on Camano Island in Washington state, so I set out to find a  project CT90's to bring back to life and ended up running into a guy who had three non running project CT90's he wanted to get rid of and offered me a deal I couldn't refuse. Along the way I found that I really enjoyed working on these bikes and have now somehow man...
