 Folks 

Pictures show lightened crank in my turbo motor and missing tooth. A small bolt fell into engine. Result snapped camchain and tooth off crank. Consensus seems to be take off sharp bit and rebuild. Opinions?

- what is the alternative: new main journals? 

? ? ? - its a one piece crank! 

Whether a reliable weld could be achieved is questionable - failure could be again worse than the repair. Would I chance it unrepaired - maybe in a streetbike / daily hack but a turbo bike - hmmm, I don't think so! Best ask a crank builder / expert . . . . Rupperton would be a good shout!

As Ian said I would never run that, also turbo motor so use stock crank.

Slightly different but mate had quacker seize on him big end picked up. He had crank metal sprayed, he's not fast rider at all but I still pulled a face. Not something I'd do. Maybe at work on a big machine thats very slow rpm perhaps.

Yep it lasted about 2 days.
