I recently got a 2001 WR426 that was halfway converted to a YZF. Well the plastics and got rid of light at least. I took it to the track last weekend had no problems through the turns and climbing the steep hills but wasn't able to really get any air on the jumps. I was maintaining the same amount of speed as lot of the other riders but only landing half as far. Do you have to preload the suspension? Should the suspension be soft or stiff for the track? It set up pretty soft now. Any suggestions? Thanks,

yeah, you need your suspension set up to your weight and skill level.

when i run my desert set up it's so spongy on a track. i can't clear much, but when i adjust the clickers to a more moto style set up i can easily clear everything at much lower speeds.

pre loading is a big part of it as well but that almost happens naturally as your bike compresses going up the jump face. in more technical sections you will have to seat bounce your bike to get over jumps that are right after corners that you can't get a good run at.

hit up your local yamaha dealer or post your location online and someone can direct you to a suspension expert in your area.

There are a lot of things that feed into getting adequate distance off a jump that have nothing to do with the bike, and speed is only one of them. Since most of it is riding technique, it's a better question to ask in the MX Riding Technique Forum. But, one of the things you will notice is that accelerating up the ramp, rather than simply holding a speed, will extend the distance somewhat. Note that actually leaving the crest with the power on will tend to raise the wheel, just as chopping the throttle will drop the nose, so you need to learn when and how much to roll off to control your attitude. Pre-loading helps too, as does position on the bike.

Suspension needs to be sprung and damped well enough that the rear just does bottom on the hardest landings. Stiffer than that, and you aren't getting the full benefit of the suspension travel. As far as the rest of the setup, that is governed by handling considerations other than performance over jumps.
