Looking for some tips on what I should go through as a checklist on an '01 YZ426 I bought. Aside from the obvious things to look for like leaking fork seals, seepage at the radiator/water pump connections, fork/shock action, spokes/rims, etc., what are some other things to look for that could point to existing or potential problems? I'm not mechanically inclined to the point where I'm comfortable tearing into the engine, but I can turn a wrench and do some of the simpler stuff. I already have the JD jet kit in mind, since I'm likely to do most of my riding around 5-10k feet here in CO. Maybe an air filter and the PowerCore IV pipe that I had on my WR. Probably need stiffer front/rear springs from stock, since my geared-up weight is around 220. Thanks.
