Currently running a 2014 Pro RMK 800 with a Boondocker kit. Replaced quick drive belt system with TKI belt drive system (HUGE Improvement) running a 2.25 gear ratio I do believe. Looking into rebuilding motor for preventative maintenance and possibly saving in the long run. Probably will throw in v-force reeds and the new Polaris series 7, 3" track. Any ideas on a better crank and better Pistons? What do I need to do from this point to make this thing durable. Probably won't run straight race gas but it would be cool for the hell of it. Don't want to break a skirt or the crank. Polaris probs. Sled has 650 miles and had been run from 6-10 pounds of boost. 10 only when needed in sticky situations.
