i was just given a 2003 500 rubicon and was told 2 different things about the atv. One brother said it had coolant leaking out of the exhaust and the other said it had low compression. Both opinions are from not very mechanically inclined individuals so i am going to start out knowing nothing. It has not run in 2 years and i have no key. So last night i ordered a manual and new ignition switch. I plan on doing a compression test and charge/purchase a new battery and just see what it will do.I can see a axle seal leak on the rear axle opposite the brakes and have already found a kit, just waiting to see if it will run. i have already pulled all the trim off and am going seal up airbox and pressure wash the motor and frame and pull the radiator off and gently clean and test for leaks, test radiator fan and do what i can while parts are shipped.
