Some questions that I have: Anybody had good luck with Tusk Racing reusable stainless oil filter? What kind of oil do you run in the filter? I have read about lots of problems with the chain guide. Anyone try the Polisport product that replaces the stock plastic that fits in the stock metal guide? Aside from a few small items, I plan on riding the bike stock a little this fall and then plucking away at some upgrades over the winter.
