Increase your top or bottom end performance by up to 10% by upgrading to an adjustable cam sprocket.

An easy mod for a noticable increase in throttle response or high end RPM.

HOW IT WORKS

Anticlockwise Rotation - Advances the camshaft causing the valves to open and close sooner resulting in an increase in bottom end power and a decrease in top end power.

Clockwise Rotation - Causes the valves to open and closer later resulting in more top end power with a reduction in low end torque.

NOTE: Recommended for poeple with engine tuning experience.

HOW TO ADJUST

Standard setting for CRF 110 & 125F models is the centre mark.

Start by adjusting the sprocket one or two marks in either direction depending on your desired outcome.

Tighten all bolts and with loctite and make sure your engine turns over without issue or check the valve clearances before testing.
