Thanks everyone for the tips,the reason for asking is I had my MB Yamaha crank twist on me and I couldn't true it up because the pin moved with a hammer so I took it to a local bike engineer who knows his stuff to have it split,rebuilt and welded but it distorted out of true when he TIG'd it and it would not true up.He has done some for me in the past and they have all been fine.
