T120TT Amal monobloc 389 carb set carburetor set right-left 1 3/16" bore Triumph T120 TT
Set of new Amal 389 mono bloc carburetors with a 1 3/16" bore. You will receive 2 left hand carbs. It will fit a Triumph 650 T120TT from 63-67. However if you are running low compression pre unit pistons you may want to run a smaller carb. The Amal company is fitting these carbs with # 4 slide, 330 main jet, a 106 needle jet and a 25 pilot jet. Directions and maintenance are included in the box. Please refer to your factory parts manual and workshop manual for specifications. We can change the jets for you if need be but you must ask at the time of purchase. Amal carbs do get to the point where they cannot be rebuilt but Triumphs are reliable when everything is correct. If your carbs are the originals and have high mileage it may be time.
