I have never gotten the KR to work for me.. I bought one 12t Double for touring mod and my monster stock is just as fast as it. It over heats really quickly.. Ive trued the comm and lubed everything up but still runs like crap.. And the brush hoods are really tight on the brushes, to the point that I have to file the brushes down just to get them in the motor without them binding... Anyone else have problems like this with the KR?
