Frequently Asked Questions

What common issue can cause motorcycle engine base gasket leaks?

Motorcycle engine base gasket leaks can often be caused by using acorn nuts. These nuts have shallow threads, causing the stud to bottom out before the nut is fully tightened, preventing a proper seal. Using standard Harley-Davidson nuts is recommended for a secure seal.

What are the consequences of a broken shifter fork in a motorcycle transmission?

A broken shifter fork can lead to a catastrophic transmission failure. It can cause one shifter clutch to engage a gear while another is in a different gear, locking up the transmission. This can break the countershaft, damage the case, lock the rear wheel, and potentially cause an accident.

How much does Dragonman charge for a 'rebuild your own motor' service?

Dragonman's 'rebuild your own motor' service is priced at $1200. This includes a gasket set and Hastings rings. Optional new springs are available for an additional $65.

What is included in Dragonman's top-end rebuild service?

Dragonman's top-end rebuild service includes valves, guides, glass beading, a two-angle valve job, new valve seals, bored outcast pistons, Hastings rings, and options for 8.5:1 or 12:1 compression pistons, all for $450 parts and labor.

What is Dragonman's advice for older motorcycle transmissions?

Dragonman advises that motorcycle transmissions over 30 years old should be taken apart and thoroughly inspected to prevent failures like broken shifter forks and case damage. Regular checks can help avoid serious accidents.
