Cylinder Oil Passage Drain Tube, Also Known As Pig Tails (L6C)

St. Paul Harley-Davidson / Buell


Evolution cylinder oil passage drain tube kit for stock bore size cylinders only. When you are replacing your cylinder base gaskets this is a great kit to install. This will eliminate the oil from ever touching you base gaskets again by sending the oil down through the tube pass the gasket and into the lower end of the engine.

Easy to install. With the cylinders off just tap the oil drain tubes and insert the tube in to the cylinder. You will still use the cylinder base gasket but the returning oil from the top end will never touch it.

The kit is supplied with two drain tubes only.

You will be supplying your own allen wrench and tap.
