ok experts, I have a 04 500 H0 The starter or starter drive seems to stay engaged to long after realeasing the key giving it a little fuel fixes it instantly, seems like the spring is to weak to pull it off the flywheel ? I want to fix this problem cause this is my spare quad that several people ride and explaning this to a female is not easy !! I need it to start like a car. What should I change I am about to order a new drive, Just wondering if anybody has had the same problem and what is the fix ? Also how difficult is it to change the drive ?
