I need the aluminum rear master cylinder guard/cover for a 99 yz400. If anyone has one to spare, let me know what you want for it. They're a little pricey new.

I just had to replace the front fork seals on this '99 I've had for about 4 months. Don't know when/if they were replaced previously. Is it a recurring problem with these flipped forks and (if so) how often?

Desperado. The fork seals on my 99 are original. So is the oil for that matter. Yours might have just worn out or there could have been calcium deposits on the fork legs from washing the bike and not drying the fork legs off. The calcium deposits eat up the fork seals or so I've read.

So wiping the forks off after washing the bike is a good idea huh. What about spraying WD-40 on them or something else?
