DESCRIPTION
All EVP.MOde Spec TAPP primaries are calibrated with +2mm rollers. Bigger rollers make the low end quicker RPM's, shift out quicker, and lower the full-shift RPM. This is due to arm angle and roller weight differences.
- +1mm Rollers - Outside Diameter 16.5 mm; weight 12.5 grams each.
- +2mm Rollers - Outside Diameter 17.5 mm; weight 15.3 grams each.
- +3mm Rollers - Outside Diameter 18.5 mm; weight of 18.5
- +3.5mm Rollers - Outside Diameter 19mm; weight of 19.7
IMPORTANT - Roller size must be installed in pairs opposite each other. Failure to do so can imbalance the clutch and may cause failure.
