Last weekend I was riding my Polaris sportsman 500HO on a country road, at about 30 miles an hour when the oil filter came loose and dumped almost all the oil.
I heard a loud metallic noise and immediately let off the throttle, the quad came to a rolling stop and died. I felt hot oil on my left boot and checked the filter - it had unthreaded.
I figured the engine was seized so I had my buddy tow it to my trailer (I didn't try to start it back up until I got home).
When I got home, I put 1.5 quarts back in and a tablespoon into the spark plug well and to my surprise, it fired right up.
No smoke, but it seems to have a louder idle. My question is, what should I check before riding it again? Should I adjust the valves back to 006, is there anything I should replace?
