Honda tires

Q: I have owned my Honda CB450 since 1970. I have just started working to restore it. This model was the first 5-speed 450 made, and it came out with a 3.25 x 18-inch ribbed front tire. I’m not having any luck finding this size tire on the internet. Do you have any resources that I can contact?

A: If you’re set on having the classic tread pattern, try Sirius Consolidated Inc. (siriusconinc.com). They sell Liberty tires in classic patterns. If modern tread patterns are OK, Michelin makes a Road Classic line that has a tire in that size. You’ll have to ask for 100/90-18 as they don’t size by inch anymore.

Trident troubles

Q: Hello, I am working on a 1974 Triumph Trident. When I received the bike it did not have an auto advance or plate installed so I bought the parts. When I was going to install the auto advance I noticed there is no notch or pin for the auto advance to install to. It’s just a conical shape that has a center bolt as I’m sure you know. It does have a notch on the conical shape of the auto advance piece, but nothing inside the hole of the engine to line it up to. I’m curious how to install the auto advance to make sure it’s in the correct position.
