[QUOTE="dirt bike dave, post: 1256415, member: 18302"] At least part of why your rebounds seems so slow and the front of the bike sags so much is your bike has very soft fork springs for its weight. FWIW, I would not give too much weight to how the bike feels when you are pushing it up and down in your driveway. How it works on the trail is far more important! I had a '91 KDX250 and the stock fork settings are not good at all. As with other KDX's, the bike has too much high speed compression damping and too soft a spring. This is fine on the street (KDX's are dual sported in many parts of the world) but bad off road, as you are too soft for jumps and big whoops (springs too soft), but too stiff on rocks and roots (too much high speed compression damping). On mine, I revalved the fork with a Race Tech gold valve, put in stiffer (but not too stiff springs, .40 kg/mm, I think). I also had no pre-load on the new springs, as this help the front end dive down for tight corners (the stock steering geometry is very slow). This greatly improved the bike. I really enjoyed mine, but the bike takes a little more effort to set up properly than most others. The stock jetting and forks are especially bad. It is also hard to get your weight forward, but this can be improved by removing some foam from the front portion of the seat. After some tuning, the motor was very smooth and already has a heavy flywheel weight. You can get more low end by using a thin head gasket from a '88 KX250, and it will still run fine on pump premium. If you want to replace the front lower fork guards and can't find a listing for KDX250, I think the ones from a KLX250 or 300 will fit just fine. [/QUOTE]
