The best launches I got out of my recon and my brother's 250ex is to rev it up a LITTLE (don't bounce it off the rev limiter) and pop the clutch in 2nd (i know, it's an auto clutch, but you know what I mean). 1st gear is just too low to get a good launch.
Your pretty much right on the answer, but at the gate try rolling your quad back and forth a bit to set the tire tread's down inside the ground a little, when the card is turned sideway's get your engine rpm's around 4000 and keep your eye's on the gate, soon as the gate drop's drop the clutch and let the quad take off on it's own for about a sec (enough time to roll the tire's instead of spin) then punch the gas wide open and go threw the gear's for the holeshot. Keep in mind, you'll alway's want to start in 2nd gear.
The best thing I can say to ride fast is to get to know the track good first, and then just totally push it to the limit. If you're not going wide open throttle, then you're on the brakes as hard as you can, then back on the throttle 100% again as you come out of the corner.
Again i 95% agree.
The first time i even seen an MX Track in person was the first time i ever actually really pushed a quad. Of course i was a little scared, who wouldnt be after seeing a 70' table top for the first time and knew they had to jump the entire thing?
After finally saying f**k fear, i rolled onto the track (planned to ease around it a few lap's to get the rythm of it) but wen't into the first turn wide open. Really didnt realize how close the first jump was (40' Table) untill i came out of the turn and your already on it. Zoom'd over it wide open and made an almost perfect landing, so i then just went wide open all around the track.
Best thing you can do over the jump's is make d@mn sure your commonsense will come into play because one mess up and your gonna get hurt.
People talk about landing their quad's on the rear tire's first, NOOOO, you wan't all four tire's to land pretty much at the same time if not at the same time. When landing rear tire's first, it will slam the frontend down and throw it back up making it wheelie coming off the jump. When landing front tire's first, it's either gonna cause you to turn it from all the weight behind pushing on the tire's and it will slam the rear tire's down causing you to lose a bit of speed by bounching the rear end off the ground a few time's creating wheel spin.
Another thing is, when you first feel your in the air off a jump, let completely off the gas then when you think your about a foot off the ground nail the throttle, it will give you a gain of speed from not spinning the tire's.
But all in all, you really dont want to get that much air on a Utility Quad.
