TEAM RAMP ANGLES
The angles and length of the transition between the first
and final angle is stamped on the back of the helix. The
first number (A) designates the starting angle of the
ramp. The second number (B) designates the finish
angle. The last number (C) is the transition distance (in
inches) between the starting and finish angles.
IMPORTANT
Do not install a non-ER helix on a PERC-equipped
snowmobile where the engine changes directions.
