10.  Install one billet tip on each heatshield making sure the ends of the tips are parallel with each other.  

On Slashdown models, make sure the angled ends of the tips are parallel with each other.  Fasten the 
tips with the supplied ¼” x 20 buttonhead screws making sure they snug up against the heatshield 
leaving no gap between the tip and heatshield when tightened.  

If it is difficult to slide the tips into 

the heatshields loosen the clamps on the heatshield and adjust until aligned, avoiding this may 
cause damage to the chrome tips

11.  Tighten the clamps on the heatshields. 

12.  Reinstall the right side floorboard assembly; tighten the bolts to factory specifications. 

13.  Make sure all the hardware (brackets, headpipes, heatshields, and baffles) have been tightened and 

cleaned before starting the motorcycle. 

 

  

IMPORTANT: 

 Cobra highly recommends using a Fi2000 Fuel Management System to help 

eliminate lean conditions and popping sounds.  Cobra Part# 92-1968.

 

Before starting your engine remove all fingerprints from chrome with a quality wax or chrome polish.  
Failure to do so can cause discoloration.  Due to fluctuations in fuel injection/carburetion settings, 
timing, etc., Cobra Engineering does not warrant against chrome discoloration.
