barrel valve
One of the exclusively SCE engineered part for Top Fuel bikes, usable for Twins as well as for Four cylinders. This part controls the amount of fuel on idle rpm as well as on full throttle in the (mandatory mechanical) fuel system for these bikes. Possible to order in left as well as right turning. To make the right fuel air combination on idle rpm you can adjust both separate items from each other. This idle adjustment is unique for TF bikes.
