Always start with standard settings and make damping changes in no more than
two click increments and only make one change at a time.
Symptom Action
Rear end feels stiff on small bumps
Softer compression damping
Rear end ‘sways’ on straights
Harder compression damping
Bike tends to jump ‘rear end high’
Harder rebound damping
Bike tends to jump ‘rear end low’
Softer rebound damping
Frequent rear end bottoming
Harder compression damping
Bottoms after end of continuous bumps
Softer rebound damping
Rear end ‘kicks’ over square edge bumps
1) Harder rebound, 2) Softer
Compression
Proactive Suspension Adjustments
Once you have the suspension adjusted for decent overall feel, you can make
proactive adjustments when faced with different racing conditions.
Situation Actions
Sand track
Lower the rear end (increase race sag).
Sand track

Long fast track
Lower the forks in the clamps by 3 mm.
Tight slow track
Raise the forks in the clamps by 3 mm.
Mud track
Lower the bike if the rider has difficulties
touching the ground.
Carburetion
Although your Cobra is sent from the factory with the carburetor jetted for optimal
performance, you may find it necessary to adjustment your particular jetting due to
current weather conditions, altitude, fuel variations, and/or engine modifications.
CAUTION:
Proper jetting is very
important for engine performance and engine life. Symptoms
of improper jetting are listed below.
