NORAM Cheetah Clutch Engagement Adjustment

Postby cutpriceracing » Sun May 11, 2014 7:05 am

The Cheetah Racing Clutch is set at the factory to engage at 4000 rpm. Although many
racers find this to be the optimal setting some require a lower engagement. Because of
the Cheetah’s design the engagement of the clutch can be altered very quickly and easily.
There are two features of the Cheetah clutch that allow you to make engagement
adjustments. The first is the cam weight design. The clutch contains six cam weights
and each cam weight has a small hole in it. Weights can be added to each cam. The
second feature is six springs located next to the cam weights. These springs can be
adjusted to change the engagement speed.

3500 RPM Engagement Setting
By adding weights to the cams the engagement can be changed to 3500 rpm. The
weights for a 3500 rpm engagement consist of six (6) #10 screws and six locking nuts.
The amount of weight added is 10 grams per cam. Locking nuts must be used to
ensure the weights do not come off during use.

To achieve an engagement of 2800 rpm include a washer with the screw and nut
assembly. Washers should be placed on all six cam weights. The amount of weight
added is 16 grams per cam.

must be used and all six springs must be adjusted. Using a 3mm hex wrench turn each
screw one complete turn counter clockwise. The gap should be 7.0 mm.

Returning Springs to Stock Setting

2. Install new spring, washer and screw.
3. Tighten screw so until the top of the screw is .41 inches in height as measured with a caliper.
*NOTE* This is approximately 5 full turns back out from fully tightened position.
