NOS Dellorto factory 11gr. Brass float for model SSF 22/25mm carbs with intergrated float bowls. These floats do not fit SS/SSI/SS1 carbs that use the larger 14gr floats or the SS1/SS2 remote float bowls. Floats have a 35mm OD and Dellorto part number 1311. Original brass floats are hard to find and in very limited supply.
