01 Forman Rubicon 500, had coolant in oil, so I tore it down, the cam lobes where chewed up picked up a used one, cam chain was also garbage, water pump bearing was toast. So while in there I replaced the rings, got it all back together and runs good, except I forgot to check the head if it's warped! Needless to say coolant is seeping out on the lowest side of head when running. So what's a good head gasket? I used a after market one
Battery load test was good + full charge. Have not adjusted clutch. I ordered an O.E.M. angle sensor But will look up how to adjust clutch before installing sensor.

Awesome, happy for you..yea, meltav helped me take the ECM plunge with the green coil wire to ground test, amazing to think NON OEM can wreck such havoc, here's to many trails and memories 😊
It is a rubber material and very flexible. About 3/16”. I wanted something thicker but the thicker mat that was in the store already was cracked as it was rolled up and would probably rip easily on the trail. I haven’t trail tested this hard yet so I will see how it holds up and report back after deer season starts in August.
