This pair of AMAL MKI Premiere Carburetors is set up and ready-to-go right out of the box. They are jetted for vintage Triumph T120 650cc and T140 750cc Bonneville motorcycles, which are dual carb. These come equipped with a 200 main jet, .106 needle and a #3 slide. This includes one left-hand and one right-hand carburetor. If you want the best for your Triumph, this is the carb set to buy! No guesswork on jetting or slide cutaway, these are good to go.
Many old Amal carburetors are physically worn out. Common problems include a worn slide and/or a worn bore in the carburetor, causing the slide to be loose. Another common problem is that the mounting flange was overtightened, warping the body of the carburetor. All of these issues cause air to leak past the slide, causing erratic idle, hard starting and the like. These carburetors fix those issues, as they are brand new from Amal in England, original supplier of carburetors for Triumph motorcycles.
The 900 Series AMAL Carburetor has been re-designed to improve performance and wear. The new carburetor incorporates changes in materials which reduce the rate of slide and body wear and a precision engineered idle circuit which improves the pick up performance from idle and reduces fuel consumption. The precision manufactured forged alloy, hard anodized throttle slide has a low friction surface for smoother operation and greater wear resistance. The material of the carburetor body has a "passivated" finish which resists corrosion, while the ethanol resistant, puncture proof StayUp float and viton tipped alloy needle valve improve control of the fuel flow.
A new easily removable pilot jet provides precise metering of the idle circuit. The jet, which is located in the opposite position to the pilot air screw, is manufactured to tight tolerances allowing it to be replaced with minimum disruption to the adjustment of the carburetor. The size of the jet replicates the 622/107 pilot bush. Removal of the jet allows access to the rest of the idle circuit for servicing. The new jet cannot be fitted to earlier versions of the Mk1 Concentric. For your reference, a right side carb has the tickler on the right side of the carb body, on a left side carb the tickler is on the left.
