Vincent Engine Breather. Vincent Motorcycle Elephant Trunk Breather Kit

Description

Norton riders often ask. Is your Vincent out of oil?
The Crankcase Breather Modification is a must for your Vincent.
When you park your Vincent is there more than Six drops of oil under your bike? If the answer is yes, you need a Breather.
When you Park your Vincent have you received the Valdez award?
This Breather with the addition of the one way check valve has helped stop my Vincent's from hemorrhaging oil by over 95%.
This Breather installed
correctly
doubles the Crankcase volume and gives the displaced air inside the motor a place to go
instead
of blowing out of your ET172/2 Valve Lifter Cable Abutment and your Stock breather tube.

The reed valve has two ends. One white and one black. The white end has a 2 inch piece of 1/2 hose preinstalled on it .
The 1/2 inch hose acts as a manifold and pushes it to the 3/4 inch hose. Remember to hide the Reed Valve behind the seat stay.
The 18 inch piece of 1/2 hose attaches to the black end of the Reed Valve. From there rout the 1/2 hose past your rear axial.
