How are y'all getting the belt to hold up on the K9? The K9 has a 1" belt going to the rear. My 04 chopper has a 1 1/4" belt going to the rear pully. I also have both new pullys. One coming off the transmission and a new Mad Clown pully on the rear wheel. With the belt properly adjusted. If I romp on it from a dead stop or at any speed under 20 mph most of the times my rear belt will jump a tooth. And yes my belt is new also. Now I have a 107 motor. Have not Dynoed the bike but S&S says this motor should be putting out around 105 - 110 hp. So if y'all are dynoing 133hp how are y'all keeping the belt from jumping teeth???? Also I'm running a BDL open primary with a ball bearing lock up clutch. That might explain why there is no give for slippage!
