Hey, My bike is due for it's first oil change and I want to get only the best stuff for it. It's a 2004 WR450F. Where can I get a magnetic drain plug, good oil filter (which is better, paper or the reusable metal kind and from who?) and what oil do you use? I'm thinking of using synthetic. Are K&N oil filters pretty good? Are they reusable? I like the thought of a reusable oil filter just because I don't have to make a trip to the dealer and buy one all the time but it just seems like they should be tossed out after a few uses? I dunno, maybe it's just me. Thanks everyone for their input!
