I'm looking for anyone else who has had to replace the crankshaft in their 08's.

 

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.

+1, on lugging motor....

 

Right here, I'm NO lugger! $hit happens!

 

I had a growth on the end of mine in my 20's, but a shot from the doc had it cleared up in about 2 weeks.

 

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.

 

So how bad does it shake? At .009 I'd think it would shake pretty good.
