I don't want to sound stupid but what do you guys do to your bikes as far as normal preventative maintenance goes? I've always owned 2 strokes and will never go back now but I didn't have to do that much to those to keep them running. Now that I have a large investment (for me) into my bike how can I keep it running. It's a 99' yz400. I change the oil every hard ride but haven't done much else besides torquing bolts here and there. I'm really mechanically inclined, I just don't know what the common things to check on this bike are seeing as how it's new to me and you all seem very knowledgable. Thanks, Khris ------------------ When in doubt, GAS IT!
