Our instructional videos contain the same information we have taught for over 14 years in our intensive 4 day Hands-On Workshops at our shop in Ohio: Motorcycle repair, Harley engine overhaul, Harley engine building, custom motorcycle building, troubleshooting, and video lectures on the 28 textbooks that go with our professional motorcycle mechanics courses.

Years of painstaking work went into the production of these high-quality instructional videos. You will not be disappointed!

All mechanical procedures and motorcycle mechanics theory is covered step-by-step, and part-by-part on all our videos. No steps or parts are skipped. Important theory and technical concepts are taught in great detail.

We take the mystery out of learning motorcycle mechanics. Tired of watching instructional videos where instructors talk forever and don’t get down to showing you what to do? We don’t do that. We’re not going to waste your time like that.

We don’t just “tell you” what to do, WE SHOW YOU HOW TO DO IT! Our philosophy is this: “If you can VISUALIZE IT, you can DO IT!” If you can watch procedures performed right in front of you, it becomes a “no-brainer”. You can then perform the procedures yourself. Just like an apprentice, you learn by watching someone with years of real-world experience.

Our extensive list of instructional videos also includes “Classroom Lectures” on most of our 28 textbooks on motorcycle mechanics theory, troubleshooting, repair, and many related topics.

Harley Engine Top-End Teardown & Reassembly


These videos instruct the student in proper teardown and rebuild of the top-end. This is a “dry-run” in preparation for the Top-end Overhaul video series on overhauling engines. These videos give the student a comfort level, and a slower “ramp up” in understanding the issues involved with top-end teardown, and top-end rebuild, before starting to learn top-end overhaul procedures. Otherwise, we felt that the student would be overwhelmed by combining engine theory, top-end teardown, detailed top-end overhaul procedures, and top-end reassembly all in one huge video series.
