bumping this back up for you to get some more responses---
some riders have had crank problems after performance work.
"lugging" the motor can cause fatal crank problems- if you are a 'lugger" that could be the source.

I did on my 09. 18k miles. Bike was a stock Stage One with NO cams, etc.
When I fixed it... I fixed it alright! HAHA! Since I had to split the cases anyways... made the bike into a 107, with a welded crank from R&R, and that bike lasted way past 50k when it got repoed.
Doing that build was FUN! I did it all myself in the garage. My current bike is a 120r. I did that myself in the garage, too. Once bitten by the performance bug, there is no going back!!!

Why did you have to replace it? What was wrong?
I had the SE compensator installed on my 08 RKC at around 72,000 miles. The service writer told me I needed an engine rebuild because the crank was out of round .009 Had me come in and have the mechanic show me. I asked the mechanic what the tolerance was and he said .012. Still in tolerance so I told him to put it back together. It's got 91,000 miles now and still running great.
