Cowl Assembly
1. Use a Dremel cutting tool to rough
cut the cowl for clearance for the
exhaust system and for additional
cooling. The air exit hole must be
larger in diameter then the air inlet
for sufficient cooling. Remove any
rough edges with sandpaper.
Note: Avoid
sharp corners
to prevent
stress cracking
from vibration.
Extend a ball driver tool by cutting
standard ball driver in half and adding
a section of copper tubing a small
heat shrink tubing.
2. Install the plastic cooling air
deflector(only offer for 107-122”
decathlon) to the inside of the cowl.
Secure with thick CA or silicone. Some
trimming might be necessary for
clearance with the engine.
Note: An extended Allen wrench is
needed to reach the hardware to
remove and install the cowl.
