FOR TRIUMPH BONNEVILLE, THRUXTON, SCRAMBLER, AMERICA AND SPEEDMASTER
All-billet CNC-machined aluminum choke knobs for Keihin CVK carburetors and CTK EFI
Feature special 3-D CNC-engraving on "900" series and "Joker" series knobs
Simply unscrew the existing black plastic unit found on your stock carb and install one of these Joker knobs in its place
Includes stainless steel threaded (M4 x .7mm) stud, and alignment of engraving (and tightness) is achieved by using a special serrated bellville washer
Notched cuts on outside really improve grip of the knob
Works perfectly on the new EFI - CTK "carbs" with the two-stage fast idle
