Clutch Ramps, Set of 4, for TAPP Primary

Your EVP.MOde Spec TAPP clutch comes with a set of (4) pre-chosen ramps that have been tested in many scenarios and have been deemed to be the most generic in most situations. Each ramp has an “A” profile side and “B” profile side. “A” side will always be lower engagement, “B” side will be higher engagement. Changing the profile of the ramp will have many effects on the shift profile including engagement rpm and back shift. This should only be done by an experienced tuner.

IMPORTANT - Always adjust the ramp profile in pairs across from each other, if you do not the clutch will be out of balance.

RAMP PROFILE	A Side B Side	ENGAGEMENT
1328 Convex	A Side 2900+ RPM B Side 4500+ RPM	Medium/High
1335 Concave	A Side 1700+ RPM B Side 2400+ RPM	Low/Medium

Flipping 2 ramps from “A” side to “B” side will increase your engagement roughly 600-800rpm.
Flipping all 4 ramps from “A” side to “B” side will increase your engagement roughly 1200-1600rpm.

DESCRIPTION

Your EVP.MOde Spec TAPP clutch comes with a set of (4) pre-chosen ramps that have been tested in many scenarios and have been deemed to be the most generic in most situations. Each ramp has an 'A' profile side and 'B' profile side. 'A' side will always be lower engagement, 'B' side will be higher engagement. Changing the profile of the ramp will have many effects on the shift profile including engagement rpm and back shift. This should only be done by an experienced tuner.
IMPORTANT - Always adjust the ramp profile in pairs across from each other, if you do not the clutch will be out of balance.

RAMP PROFILE	A Side B Side	ENGAGEMENT
1328 Convex	A Side 2900+ RPM B Side 4500+ RPM	Medium/High
1335 Concave	A Side 1700+ RPM B Side 2400+ RPM	Low/Medium

Flipping 2 ramps from 'A' side to 'B' side will increase your engagement roughly 600-800rpm.
Flipping all 4 ramps from 'A' side to 'B' side will increase your engagement roughly 1200-1600rpm.

Adjusting Ramp Angle:
The ramp angle in your TAPP Clutch is adjustable from the outside via the use of the Quick Shift Bolts. As with other clicker style clutches the higher the number, the higher the RPM. This will mainly affect the full shift speed but also affects the engagement and low speed slightly. On the TAPP clutch each ramp has its own quick clicker adjustments. Each clicker has (6) adjustments. Each click will add or subtract 25 RPM but they need to be done opposite pairs actually adding/subtracting 50 RPM.

IMPORTANT - Always adjust the ramp angle in pairs across from each other, if you do not the clutch will be out of balance.
