400ex??

I have a 2000 400EX and was wandering what all I should make sure that I'm greasing on it? I change the oil quite often and make sure my air filter is always clean before I take it out riding Also, is there anything that I should do to any other parts to help them out. Thanks for any help!!!!

A-arm bushings, front and rear shock mounts, rear suspension linkage (bushings), and a thin layer of grease around your air filter mount, to help keep dust/dirt out.

Note: I've read not to use WD-40 on your o-ring chain.

Hope this helps.
