Top End Repair  (DVD 12  72 minutes) If you're tired of dealing with those leaky base gaskets, your about to discover how  quickly and easily you can do this repair on your own. The Evo engine is one of the most reliable, easy to work on engines Harley has ever put together. However, base cylinder gaskets are a weak point. One reason this engine develops base leaks is because we don't let the engine warm up enough. You see, this is an aluminum engine and it needs to warm up and expand before you go blasting down the road, or you will stand a good chance of blowing those gaskets. In this  detailed DVD Jack will show you how easy it is to solve this recurring problem, and how to prevent it from happening again! He'll show how to inspect and/or replace pistons, rings, and wrist pins. Plus the proper sequence for reassembly and the correct method to use when you torque the head bolts.
