Our Mikuni Carburetor Kit was specifically developed for the carburated models (2001-2008) of the modern classic Triumph Bonneville (Bonneville, Thruxton, Scrambler, America, Speedmaster) and is designed and manufactured exclusively for Bonneville Performance. It consists of twin 42mm HSR Mikuni carburetors jetted for your bike, CNC machined billet manifolds, airbox/air filter adapters, top and bottom braces. It also includes o-rings, throttle control rod for carbs, all fasteners and throttle cables. A single pull twin cable choke (enricher) is also included.
This is a bolt on kit. For best performance we recommend an aftermarket tuned exhaust system. We have utilized BUB’s and Specialty Spares exhaust systems while testing the performance of this carb kit. Customers report positive results using BC Predators or SBT Dominators.
If you are tired of erratic idle speed, sluggish response and the general unpredictable behavior of your stock Keihin CV’s, this kit is your answer for rock solid performance at low, mid and top end RPM ranges.
