If you have an Evolution with about 20,000 miles on it, you have a base gasket leak! The factory has tried to remedy this problem with at least four different styles of cylinder studs to no avail. Eliminates top end drain back oil from even touching the base gasket. For best results use with metal base gaskets.
Tap the cylinder in the top end oil drain back hole with the supplied aluminum tap and install the PigTail. With about one inch left protruding to be inserted into the crankcase.
Can be easily removed for cylinder service. Designed for OE style cylinders (not intented for big bore cylinders). HARDWARE Complete Kit Fits Big Twin Evolution 1984/1999 & Sportster Evolution 1986/Later.
