    Wondering if anybody has had a similar issue, I have a 1998 xplorer 400 two stroke and it hasn’t been able to hold a charge in many years. It was my dads quad before and he has changed the regulator and the stator once. He did say he had someone rebuild most of the flywheel casing because it got...

    I've got a 98 Xplorer 400 4x4. It's got 1 brake handle with a master cylinder that from what I understand operates the 2 front brakes and the 1 rear brake all simultaneously. The rear brake also has a mechanical foot pedal as well. The rear caliper only has 1 brake hose going into it. What...

    New to the atv community and recently got a 2000 Polaris explorer 400 and figured out most of the basic maintenance from YouTube videos since I’m not really sure what I’m doing since I don’t have any experience working on arcs and this is the first I have owned.
