Question 1: I installed my new race tech springs front and rear and as you know there's no dang rebound adjustment on the forks!! The rebound is a little quick and I'm wondering if increasing the fork oil (I'm currently at 90 mm) will help. Also, race tech recommends 9/16" of preload on the front and that's way too much. With 9/16th, there's very little sag. Question 2: I've done all the so called free mods and installed the Big Gun exhaust. I've increased the main jet and she runs good, however I'd like a little snappier response down low. Does the Boysen accelerator pump make a big difference ($85)? I tried increasing the pilot jet and that didn't help a bit. Question 3: The rear brake locks up and kills the engine on steep down hills, even when I'm braking hard with the front brake. I find I've got to pull-in the clutch, rather than let the engine compression help with the braking. Actually the rear end shatters (clutch disengaged) before killing the engine. Do I just need better brake pads or am I asking too much from the rear brakes. I've got the stock sprockets and shoudl probably drop a tooth on the front . . . Other than that, the KLX is a fun bike that isn't as slow or heavier as everyone thinks. I know I've made a believer out my 450cc ridin' buddies.
