    Whats the most a stock crank can take?

    My bike has a welded clutch hub (V&H) and stock pistons and head. Thought about going up a size in the pistons and adding smoothbores. Anyone running any bigger with stock crank?

    I've been 1075, 1166 and now 1395cc with a stock un-welded crank. The only problem I had was a bearing went south on #4 rod. Who's to say what caused it?? Over 1000 runs, 12K rpm's a few times, lack of oil or maybe 30K miles on it.

    I think some even run over 100hp worth of nitrous.

    They can take alot so you should'nt have any problems.

      Agree with Jake. If your staying with a small tire, no problem. Same for angle cut gear.
