How are you guys cleaning the stock air filter? According to the service manuel it's a throw away. I'm making final preperations for my stock pull tomorrow. I'm gonna look at the air filter after work tonight. So far I cleaned, and lubed my chain. The chain slack is with in tolerance at about 1.7 inches. I like as much slack as possible. Oh yeah, I cleaned my wheels with WD-40. That shit works like magic.
