Good looks and high quality make Keihin 33mm CRS smoothbore round slides the ideal Norton carb kit. Legal for AHMRA Bears and F750 classic racing. Unique custom made cable wheel and mounts make it possible for these to fit Commando frames & fuel tanks. Pre-jetted. These twin carbs are mechanically linked together so they come pre-sychronsized. Balance tube included.
Special custom length manifolds give plenty of frame clearance (see manifolds below). Easy access choke lever operates both carbs.
Customer feedback: “…everything fitted up well. Started instantly with little choke and quickly settled into an idle which I have not touched !… these dual Keihins are awesome, they run strong and clean with no jetting changes required, super happy with this set up.” Richard V.
