[QUOTE="dirt bike dave, post: 1430428, member: 18302"] On mine, I did gold valves in the forks, put in stiffer springs with no preload, raised the forks so about 3/8" was above the top triple clamp, and ran a WER steering damper. Had a gold valve in the shock, too, but as with other KDX models, the stock shock is better than the fork. The forks have too soft a spring, too much high speed compression damping and too soft slow speed damping, so they basically suck everywhere. The stock seat/tank junction is not good for getting forward. I shaved the seat foam down at the front of the seat and that made a nice improvement. Run a good front tire to help the front end bite as much as possible. BTW, the manual says the tank is 3.2 gallons, but my buddy and I both measured ours at 3.6 gallons. Plenty big. I found with a 1 tooth smaller front sprocket I could take 2 links out of chain and run the wheel all the way forward in the adjustments. The bike has a heavy flywheel stock, so you won't be needing a flywheel weight. A thin head gasket from an '88 KX250 will give you more compression and low end power. The steering geometry is pretty slow, so anything you can do to improve that will help. My buddy actually cut his frame and pulled in the steering angle, and that helped. He's qualified to do that kind of work, but for 99.9% of the owners, it's not worth the trouble. You can trim a little off the steering stops to get the wheel to turn more (don't go too far). On mine, I trimmed the side KIPS valves. When open, the bottom of the KIPS valve was much higher than the exhaust port. I dremeled the KIPS valve so when open it was flush with the exhaust port. The stock pipe and silencer weigh a ton. I ran an FMF pipe, and modified an aftermarket slilencer for an '89 - '94 KDX200 to fit. You can remove the rear fender supports to save a few pounds, but don't run a fender mounted tool bag if you do this. The bike is heavy, for sure. Wet, no gas and set up for trail it will probably be about 255 lbs. I had mine dual sported, and it was about 260 with the stock pipe/silencer on it. [/QUOTE]
