If you check out photos of old Harley drag bikes they often had the trusty Linkerts swapped for flashy AMAL carbs and you bet that this wasn’t just for the looks. In their heyday AMALs were considered as performance carbs and they proved countless times that they were. Simple to tune and easy to service they soon became the preferred choice of racers and speed-oriented street bikers.
The AMAL Concentric Mk1 was introduced in 1966 and was a long awaited improvement of its predecessor, the Monobloc. It is smaller and lighter and has a completely concentric design. Air and idle adjusters are relocated for easy access. These current re-production "Premier Range" carburetters feature various improvements over the 1960s counterparts:
- Forged alloy, hard anodised throttle slide which has a low friction surface for smoother operation and greater wear resistance.
- Material of the carburetter body has a passivated finish which resists corrosion.
- Ethanol resistant, puncture proof Stayup float and Viton tipped alloy needle valve improve control of the fuel flow.
- Precision engineered idle circuit which improves the pick up performance from idle and reduces fuel consumption.
- Easily removable pilot jet which provides precise metering of the idle circuit.
