CLUTCHES Helix Angles and Effects
The driven clutch helix was selected for overall performance in relation to the other driven system componentsIn fine tuning situations requiring slight adjustment of engine operating RPM or improved backshift, we recommend trying helix change before changing other componentsPolaris has several helix angles available for the P-85 and Team driven clutchRefer to the chart below for specific angle effects and identification

The helix spring should always be adjusted within its limits before helix change is performedThe normal rate of change between helix angle steps is 250 RPM under full throttleThis is approximately the same result as in going from the No1 to No4 spring position (P-85)NOTE: Increasing spring tension increases engine RPMRPM changes may not be evident if other drive or driven clutch components are substandard
