SERVICES

All kits are machined and assembled in house. Our professional technicians are trained to do the job right the first time. We hold ourselves to very strict tolerances and unmatched quality. All our borings are done in house using a torque plate for the highest quality machining. All MrRPM motor kits go through extensive dyno testing and long term durability testing. We stand behind our quality and unmatched performance. We CAN take your Can-am ATV or Commander to the next level.

Our ATV 1004cc kit is designed for pure performance. This is not a direct bolt-on kit and requires extensive machine work that needs to be done to the case to accept the new larger jugs. The stock heads require welding to work at this bore size. Bigger valves, cams, and full port-n-polish work on the heads are highly recommended. This kit is designed for the 650cc and 800cc Rotax ATV engines but can be installed on the 500cc Rotax engine using a 650cc/800cc crank. Our 1004cc big bore kits are unmatched in quality and performance. Fuel/Air tuning is required after kit install.
