I've read all sorts of personal preference on chain or gear. I myself lean towards gear considering I like the Idea of never opening the cam chest again. However, has anybody ever thought of running gears on the cams and a chain on the crank. If your crank is out of spec at least you would be done pulling the cams. In my mind just changing the outer shoe would be a snap. I have 35,000 on a 2005 Classic and I'm getting ready to take this on. I bought S&S lifters, quickee pushrods, and I'm ordering gears and bearings in a 1 1/2 weeks.
