IMO only... These type of motors were intended to be used in a industrial application for mowers, snow blowers, fluid pumps, etc. Designed to run at one steady RPM to produce high torque. The HP rating is what the motor gives inside that narrow RPM range. HP can fall of dramatically above or below that RPM range. Don't be fooled by the advertised HP claim, you won't see it 90% of the time. The carbs, jetting, ignition advance, governor and linkages are all set up for optimum performance at one RPM, mostly wide open! So their not real suited for the RPM range used in a off road buggy. You can make them run, no doubt! The pavement karts have proved that but as you can see by several other continuing threads on the forum getting the power coupled up proves a real challenge in the dirt world. Clutch, gearing, torque converters all that stuff. Final costs after trial and error equals more than a brand new drop in GY6, If they out performed a GY6, you can bet your backside a whole lot of people including my self would be all over them!
