Thumb Fatigue: How to increase stamina when racing.
Thumb fatigue is a major issue with a lot of racers. Most racers will just try and get used to the battle against the thumb. Here is one tip guaranteed to help you waive goodbye to the rest of the pack. Take out your spring from the carburetor and take it to a sanding bench or wheel. Simply grind a LITTLE metal from the outer circumference of the spring. This will dramatically change the spring rate where you will not even be able to tell that you have a spring in your carburetor. You will quickly be on your way to lasting the WHOLE race and will feel that you even accelerate harder.
For further performance, purchase a thumb ease (see accessories) for a longer throttle lever that reduces effort in the throttle and feels friendlier to the thumb.

Reduce Vibration to the handlebars.
Try buying a large container of silicone sealer. Take off your handlebars and begin pumping that silicone until your bars are completely filled. Then cap the ends of the bars and put your grips back on and go riding. Riding with a thicker grip such as Oury grips will make your hands feel more comfortable and less likely to blister.

Make your bike run cooler.
The cooler you can have your engine at running temperature, the more horsepower you will have. There are several ways to cool the beast. Here are a few ways.
Purchasing a Coolhead. Coolheads holds way more water and helps cool the engine in any riding condition. Running Coolheads on your machine will significantly enhance performance by keeping your engine cooler while enabling you to change your compression with interchangeable domes.
Pro Design inline coolers are easy and inexpensive while lowering coolant temperatures by slowing down the flow of coolant on the return line of your radiator. Easy to install in minutes.
Water Wetter by Redline, is another easy addition to your machine. Simply replace your coolant with distilled water and a few caps full of Water Wetter and you can drop engine temperature. Water wetter claims that use of water wetter with distilled water will cool coolant temperatures up to 20 degrees (but we have never field tested this).
Remember: The cooler your motor is, the better it will perform.

Keep your machine clean and mud free.
Before a race with tacky soil, take a little PAM cooking spray and spray it under your fenders and your wheels. This will make it so that the mud and dirt shake off during the race and makes it a LOT easier to clean afterwards. This works for goggles too!

Bring that old plastic back to life.
Here is a way to avoid spending hundreds of dollars for new plastic. (note: This works the best with white plastic.) Take a bottle of Fantastik cleaning spray, a bottle of Dawn liquid soap and a bristled brush. (Toothbrushes or car scrubbers with large white bristles work best.) First pour some Dawn soap onto the plastic in a swirl design. Next, spray a good amount of Fantastik cleaner on top of the soap and plastic. After a few moments, begin brushing the plastic with lit pressure and work area for several minutes. Spray off with water and you will be left with a incredible shine crystal clean plastic. (Fantastik spray and Dawn cause a mixture that brings out fades and staines. Works amazing on deck furniture too.)

How to apply decals and number plates.
The first thing you want to do is to remove any old stickers or decals from the plastic with a heat gun (or a hair dryer). Then wipe the area with rubbing alcohol to get rid of all the glue residue and you are ready to go. Purchase a bottle of 409 (Windex or really soapy water will work too) and spray the area you want your decal or sticker. Place the sticker on top of the damp plastic and slide it into the desired place. Next, take a credit card, or squeegee, and begin running the card over all the area of the sticker. Be sure to careful around the edges if they are die-cuts. Wide the excess from around the sticker and look at your beautiful sticker. If by chance you somehow managed to get a air bubble, take a heat gun heat the area and work the bubble out. Now you are looking like a pro.

Fullbore shine without the Fullbore plastic.
This is simple and easy to make that machine glisten in the sun. After washing your machine, take some Pledge (I prefer lemon scent) and lightly spray over the top of your plastic. It doesn't take much to make any plastic look like a million bucks.

Out accelerate the rest of the pack.
The first lesson in acceleration is to first of all make sure your motor setup is up to snuff (i.e. air filter, pipe & silencer, porting, carb, reed cage mods), you want to learn how to shift inside the powerband. The best way to do this is to short shift the machine (not letting your machine completely over-rev) and use the clutch. If you can cut down on the time between the shift and when the motor pulls, you will be waving "bye bye" to the rest of the field. Another secret little trick exclusively from LRD Performance is the Hi-Rev CDI box for the TRX250R. This eliminates the rev-limiter while giving you 2 more H.P. from 4000 RPM and up. This will give you the extra foot to make it into the first turn and to walk away. CDI box sells for $179.95. If you are serious about wining, its not a good idea to let your competitors know about this because you will have the advantage.

Holeshots and starting.
You want to be sure to try and get a first choice for a gate pick, but most of the time it is just pure luck. At some venues, it is first come first serve and you want to have the cleanest, fastest line possible. A good place would be right in the center near the box (on the outside it can get to be loamy dirt and soft pack making it hard to accelerate). Dust off the starting platform (if it is cement) and get your quad in position about 10-12 inches behind the bar. Make sure that your quad is completely warmed up, and ready to go.
Be sure to have your body position in a neutral position at first with your elbows up. When the ten second warning has come, rev your at a about 7,000 RPM and let the clutch out just enough to start to feel it engage. When the gate does drop, gradually let the clutch out keeping the high rpm take you out of the gate (this will prevent you from spinning out or popping wheelies. Once you are on the dirt, sit farther back on the seat to get traction and begin shifting through the gears. If you feel the need to grab one more gear 20ft before the corner, keep in the gear you are in (because most will shift and loose a small amount of power at first). Once you are the first one in, make the rest of the back follow your entry, then shift and roost them. You will be on your way to a one-one race. It is always better to ride consistent and smart rather than out of control.
