Help! 2005 rev motor issues

probably got a bad stator then, they can work intermittently when they are going out,, pull the pull rope and flywheel and visually look at it..dirty, metal, broken or loose wires, burned spots ect. btw i have a flywheel and stator for sale

When my stator went out (at 2800mi) I lost my reverse,but sled still run fine. After more rideing I stopped and not thinking shut it off and it would not start again, had to get towed out about 10mi. Upon teardown my crank seal had gone bad and filled my stator/starter with grease. Luckly I caught it before it took out the bottom end. If it ran fine again I don't see how your MPEM (computer) could be bad. Pull your starter and see if its covered with grease, do a compression test and check diff from one cylinder to the other also maybe check your reeds.
