Ask A Question


Need help with vintage Hondas from the 1960s? I am an expert with 250-305cc bikes in particular and most all of the other pre-91 models, in general. I do NOT claim to have a great deal of experience on Gold Wings, Cruisers, ATC/ATVs and dirt bikes.

Experience in the area

I have owned/ridden/maintained Honda motorcycles for 35 years. I have written five books on Honda repairs and collecting. I was a service manager for two Honda shops back in the 1980s.


VJMC (Vintage Japanese Motorcycle Club) of North America


VJMC newsletter, as editor for two years and as contributing editor currently.


3 years auto shop in high school, teacher's aide in Automotive Technology in Jr. College, Diesel mechanic course in college, self-taught mechanic and automotive writer.

What do you like about this subject?

I appreciate connecting with other vintage Honda enthusiasts, anywhere in the world.

Shawn, the horn circuit is hot when the switch is ON, as you have noticed.     The power goes from battery to switch to horn circuit wire, through the horn and then the horn button completes the circuit

Bryan, You DID seize the engine momentarily. When the engine overheats, the piston gets too big for the bore and grabs the cylinder walls. Aluminum is transferred to the cylinders, the piston is gouged
