I have a 06 700 efi with about 1100 miles on it (KQ motor) I took it out riding two weeks ago and it did fine road the entire weekend no problems at all. I trailered it home and washed it like I always do. Parked it in the garage and didn't touch it for about a week. I took it out today and road my kid around for a little, killed it went inside came back out wouldn't crank. So I checked my plug fuel and air filter. All seemed to be ok but replaced the plug any way. First problem so far out of this quad. I read about a tps being adjustable but I don't know how or if I should adjust it. If you let the quad sit for about an hour it will crank up if you press the throttle a little like a old carb motor.
