Product Details
Brand: Evolution Powersports
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.
