Frequently Asked Questions

What are common issues with older motorcycle engines?

Older motorcycle engines, especially those over 30 years old, can suffer from issues like stripped threads, broken bolts, worn bearings, and damage to components like sprocket shafts and valve seats. Fuel additives can also cause pitting around valve seats.

How can catastrophic engine failure be prevented in older motorcycles?

Preventative maintenance is key. For engines over 30 years old, it's recommended to disassemble them and measure rod clearance. Worn rod bearings can lead to the rod hitting the flywheel, causing severe damage.

What specialized equipment is used for motorcycle engine repair?

Shops like Dragonman's utilize specialized machinery such as honing machines for cylinders, Bridgeport and Supermax milling machines for precision work, and welding equipment for case repairs.

What are the details for Dragonman's annual pumpkin shoot event?

The annual pumpkin shoot takes place on Saturday and Sunday, starting at 9:30 AM. The museum is open for tours at 10:00 AM on both days. Machine guns are also available for rent during the event.
