With a tuned NORAM clutch and proper gearing, you will feel an even pull
coming out of the corners and constant acceleration on the straights. For top
track performance, here are some other general guidelines to keep in mind:

Kart Chatters or Shakes
Check shoe position and try a softer, smooth setting.

Kart Bogs Down
Check shoe position.
Springs are too light; therefore, the clutch is operating
below the useful torque of the engine.

Kart Hesitates — Poor Acceleration
Spring is too light — below the useful torque.
Spring is too heavy.
Gearing is too high; add teeth to the axle sprocket.

Insufficient Straightaway Speed
Spring is too light; increase engagement.
Gearing is too low; drop teeth from axle sprocket.

Typical Clutch Set-up
Stock Racing — Heavy Shoe (QN C159).
Modified Racing — Light Shoe (QN C158).

Maintenance Tip
Clean drum and shoe — light sanding is acceptable.
Do not over-oil bearing.
