# Cometic Harley-Davidson 3 3/4in Big Bore Top End Kit For 91-Up 883 EVO Sporty

Today's lightweight engines are producing more horsepower, higher cylinder pressures, clamp loads and extreme temperatures. Our commitment is to provide innovative, quality gaskets while maximizing your engine's power and performance. Cometic's gaskets are proudly made in the USA with materials manufactured on American soil. We are constantly updating and adding models to our ever growing library of gaskets for Powersports, Street Bikes, Snowmobiles, Harley-Davidson and V-Twin applications.

-   All of Cometic's gaskets and seals have been tested on both the street and the track as well as vigorous Dyno shakedowns
-   No Additional Sealer Needed
