Hi im new here and recently purchased a 1989 FZR250R. I bought it with the engine in several boxes as 20 years ago the front sprocket came off and chewed the threads off the output shaft. the last owner stripped the engine down and had the output shaft machined down, rethreaded and a special nut made to repair it but never got round to rebuilding it. It lay in a barn for 20 years so im cleaning up and rebuiding the engine at the moment. Thankfully he purchased new genuine gaskets for it at the time. I need to source a crank seal but have started a thread for that in one of the other forums. Have been working on a rough english translation of the 250 workshop manual too, im about half way through now will post the full thing up once completed.
