Howdy, peeps. :)
Nah, I ain't jealous.
I used to own a DR-Z400SMK9, myself: ;)
There ain't any fixes like the Loctite fixes or installing a manual cam chain tensioner.
Only real potential trouble spot is the fuel pumps on some bikes get cranky and quit due to normal engine heat reducing operating clearances of critical parts on the pump and not allowing it to spin.
If Amy's WR-250X ever fails to start and you can't hear the fuel pump spinning when you first turn on the ignition switch, that's the telltale sign.
At least they usually start and run fine once it cools down for an hour.
Changing the fuel pump is fairly easy.
This was all due to a supposed batch of pumps not built to spec.
See the Sweet Mods forum on here for the mods everyone does, which are basically just typical uncorking as far as performance goes.
Also, the bikes are geared to the moon so lots of riders gear them down, too.
All I know is I'm anxious to get my own 2008 WR-250X out instead of having it sit here behind me. :)
