oil tank breather kit. Black. Dyna

Black cap. Dyna models have the oil tank mounted under the transmission. The engine, with two massive pistons going up and down, breathes in to the oil tank. This system is a way to vent the oil tank to help reduce pressure build-up and reduce power robbing pressures and stops dipstick blow-out. Comes as complete kit with filter, braided clear PVC covered lines and, if required, gaskets.
