    I’ve got a 2007 trx 250 ex when I got the thing it was stuck in gear and the guy was done fooling with it so he said. When I got it home I took the front crank case off and that immediately solved the stuck gear problem. It would shift through all five gears as long as it was open. There was...

    I’ll start with the facts and then add what I believe to be the problem. Quad was running perfect yesterday. Went to start it today, won’t start. Assumed it was a hard cold start, hooked the battery to a tender for while. Still won’t start. Rolled it around the yard in neutral to bring it...

    Dose anybody know of any cheap nerf bars with heel guards that will fit on a '03 trx300ex? or any other model of atv whose nerf bars fit a 300ex? I have heard rumors of ltz400 nerf bars fitting a 300ex. I would like to stay below $200 but could make some exceptions. Any of the ones i've found...
  8. Engine/EFI/Drivetrain
    Ok, first I have a 97 TRX300EX which has a 11:1 high compression piston and a FMF power core exhaust, and a K&N air filter with the lid off the air box. One thing I notice is that with It neutral at half throttle or so it dies off fast over and over as if it were hitting the rev eliminator...
