Mr. Data and I have been having a discussion about the run out problem on the larger 96 twin cam engines. I thought there may be some interest in the community about this information:

If I am getting into the engine to up-grade the cam shafts' drive, it is only a little more trouble to open up the engine and replace the crank shaft. Is there an aftermarket option that will not fall apart?

That was a bad deal on Mike's engine and I think the MOCO finally learned a lesson to stop cheaping out on some parts. The old adage if it ain't broke don't fix it still applies here, though. Never heard of crank problems before the 96 engines were introduced. It's going to show up after these bikes have been in service for a few more years with these cranks twisting, but hopefully people will get the extended warranty when they buy them. I bought it with mine for this very reason.

I feel lucky that I transferred the existing extended warranty when I bought my '03 (good through '10) even though it is the 88ci.
Hope some of you folks find this information useful.
