Keep in mind your suspension SHOULD bottom out 2-3 times per lap over the biggest obstacles. Most riders will want a soft suspension setup to aid in turning and bite. You want to tune it so you are utilizing the entire fork stroke on the whole track. Don't set the bike up stiff to purposely avoid bottoming because you will...

The bike is lean. increase the pilot jet and adjust your air fuel mixture screw. If the clutch is still engaging with the lever all the way in (assuming you have it properly adjusted,) that means your clutch plates are worn out and are too thin, which would not be surprising on an '08 because it's probably the factory clutch...

You're front break is causing the front end to dive (causing it to compress to about mid-stroke) and then the wheel hits chop and compresses the forks even further and it packs up. How much do you weigh? If you used the race tech spring calculator based on your weight, I would be 100x more inclined to believe their spring...

I think the Factory Edition bikes is to the point now where the few extra pounds the Estart adds is overcome by the advantages it provides in quick restarts. With Dungey, I can't think of very many times when he has straight up stalled a bike without wrecking, so we will have to see if it pays off. My big...

"Another good answer. I don't have a truing stand, it would help out of course since you then constantly would true and lace without having to take the wheel off all the time to do new measurements. I now remember using a straightedge as well, and managed to find an bolt that was 1/2 the total sum from both rim...

You really need to be using a truing stand. To measure the center, use a long straight edge resting it flat on the surface of the outsides of the hub. You can then use a tape measure to measure from the outside edge of the rim to the straight edge. If you take your time and pre-tighten the spokes in...

Yes the transport cost is paid by the rider. At our track, the injured rider can always refuse ambulance treatment and services if they are hurt in such a way that it is not an emergency or life-threataning. In alot of cases, the injured riders will have a buddy drive them to our hospital which is only about 10 minutes...

Event insurance per day is $800-$1,000. On-site ambulance is about $1,200 per day + alot more if that ambulance has to leave and bring another in return. Proper amount of equipment to run track can get to $100K really fast. For a proper sized track and parking you need at lest 50-100 acres of land at $5,000 to $10,000 per...

If you aren't looking to build a mod engine I can rebuild your engine for $150 plus parts. I live in central Illinois

Call your revalve company and explain the problem to them. Why would you start cranking on the clickers when they gave you a good setting from their company? Before you call them, measure your sag, static sag, and fork height. Tell them these numbers as your baseline and see what suggestions they have. My guess is you WILL need a...

EastFlorida I have a 2005 RM250 i'm looking to sell for $2100. It's got alot of new stuff on it and a complete rebuild one year ago. I could probably ship it if you made all the arrangements and paid for the cost. PM me if you're interested I can send pictures and details. The YZ's and RM's are very...

Don't forget to check your static sag after you set the sag again. My suspicions were you were already on the high side for sag. By my calculations given your weight you should be running 0.488 for springs (0.47 stock) and the stock shock spring is close enough at 5.5 I would recomend two sets of fork springs 1 set...

The 350sxf is not the godsend bike people thought it would be. the reason KTM sold so many of these bikes is because of agressive marketing. People are suckers for having the latest and greatest. Does anyone have information on how many yz450f's were sold when the new cylinder was introduced vs the previous model year? I bet there would...

I would start by adding some more sag to get more weight on the rear. This will somewhat free-up your front end and reduce some of the initial sag on the fork. Next step, add no more than 4 clicks of compression. If those two adjustments don't work, you need to go to a stiffer spring rate.

LAYINBODY31...i've been in the same boat as you. I went to college and graduated with a BA's degree in Engineering and have always thought about trying to do what you're looking into. I worked as a mechanic in shops all through college and one summer I was fortunate enough to do the MX series with a pro privateer. It paid...

Use a heat gun to make the material pliable around the seat bump and tight corners. What I usually do is lay the cover out on the seat and get a general idea of how the cover is going to fall with the bump positioned. Next, I apply 3m spray adhesive on the bump and about 2" to all sides...

Suzuki, RM, and Yamaha rims can all be interchanged because they all use 36 spokes. Hondas use 32 spokes. Not sure about KTM, Husky, and Gas-gas. More than likely they are 36" though. As long as you get the rim diameter and width right you don't have to pay much attention to brand specific. Spokes are more model specific because...
