CLUTCHING 9000 8000 7000 RPM 6000 5000 ENGAGEMENT 4000 3000 If the weights are too heavy, or spring rate too low, the engine RPM will be low and the drive clutch will upshift too fast, keeping the engine out of its power band9000 8000 7000 RPM 6000 5000 ENGAGEMENT 4000 3000 If the weights and spring are matched properly, the engine RPM will go to the desired range and remain there on both upshift and backshiftThe driven clutch operates in conjunction with the drive clutchIts function is to maintain drive belt tension preventing slippage, and sense variations in load requirements necessary to maintain optimum engine torque output and load requirements from the trackOutput torque is transmitted through the chaincase jackshaft and chaincase to the front drive shaft and trackWhen the load on the driven clutch is increased and becomes greater than the torque delivered from the engine, the driven clutch becomes dominant and overrides the drive clutchThe driven clutch downshifts into ratio which will match the increased loadBecause the driven clutch can sense and shift into the proper ratio, engine RPM will remain within the specified rangeENGINE OPERATING RANGE 250 RPM ENGINE OPERATING RANGE 250 RPM
