Some people may count the Polaris 800 out amongst all the 1000s and turbos now, but these are practically the most abundant ATV/UTV engine out there! They're solid and reliable for many hours, and can get right back to that with a refresh.

Nearly worthless, and will get lesser experienced people into trouble. The presenter goes right past some of the important information. What should the ring gaps be? Which direction do the pistons go? What are the torque specs? If I had a manual I wouldn't have wasted time watching this video.
