Frequently Asked Questions

What are the key services offered by Dragonman's machine shop for motorcycle engines?

Dragonman's offers comprehensive services including Twin Cam, Evo Big Twin, and Shovelhead engine rebuilds, cylinder boring, head porting, flywheel balancing, and transmission rebuilds. They also perform rocker arm rebuilds and can install features like dual spark plugs.

How should motorcycle engine parts be shipped to Dragonman's to prevent damage?

Each cylinder head and barrel should be placed in its own separate cardboard box. These individual boxes should then be consolidated into a larger shipping box. Lower ends should be secured in a plastic container or milk crate for better protection.

What is a critical maintenance check for motorcycle engines to prevent catastrophic failure?

It is crucial to check connecting rod clearance at least every 15 years by removing the front cylinder. Excessive clearance can lead to the connecting rod hitting the flywheel, causing it to break and potentially destroy the engine case.

Does Dragonman's offer services for newer Twin Cam engines, and what is advised?

Yes, Dragonman's now offers work on Evo top ends and Twin Cam engines. However, due to frequent backorders for Twin Cam parts, it is highly recommended to call ahead to confirm the availability of necessary components like pistons and valves before sending in a job.
