TAPP Clutch Engagement Adjustment
Engagement is where the machine starts to pull. On a TAPP clutch, springs and ramps control it, not shift arm weight.
Engagement is where the machine starts to pull. On a TAPP clutch, springs and ramps control it, not arm weight.
Arm weight doesn't affect engagement much. If you're trying to change where the clutch engages, adding or removing weight isn't the way to do it: change the spring or the ramps.
Springs
Springs come in different stiffnesses. The TAPP Blue is rated 100/190 and the TAPP Black 140/210, so the black spring gives higher engagement.
Ramps
Each ramp has an A side and a B side. Side B increases engagement because it has a higher shoulder to overcome before the arm roller begins shifting out along the ramp. Opposing ramps must match: two on A and two on B raises engagement, and all four on B raises it further. See TAPP Clutch Ramp Position A vs B.
What arm weight does instead
Arm weight sets top RPM. See TAPP Clutch Target RPM Calibration.
