Unfortunately I am limited to what the engine builder is dictating a bit. As for the crank, the standard crank with a standard cam is .030 out. So if that can happen with a standard crank and I put it back the way it was how long before I'm up for another engine rebuild regardless of how much power it produces?? Better off buying a Yamaha or a Victory than a twin cam with a standard crankshaft without doing at least something to stop it twisting...

I would go with an Indian before the ricearoni (not so San Francisco treat) bike, The Indian cranks are an automotive style crank with rod caps and Babbitt style bearings. If you beat the bike that hard, why not buy an S&S crate motor with a Timken bearing and far superior crank strength that will take what youre dishing out and beg for more? If it fails, you have a warranty.

I have a friend that put a Ultima 4 " crank in his TC. It's a press type and the runout was .0005" One half of a thousandth. The local shop was amazed. He hammers the motor with no I'll effects yet! I guess that's the key word. YET.

Reading this post reminded me of when I blew up my bike over 10 yrs ago. I built a 103 that produced 118hp 120tq it costs me $10K and had this company build the crank. http://www.darkhorsecrankworks.com/
If my crank runs out on my 110 I will definitely have dark horse build me anther one. I am not easy on my motors I love to beat the piss out of them.
If you're going to build it do it right!
