Looking for a shop to inspect a Honda CX500 in Portland, OR

Sun, 2006-10-29 21:56 — Sorandal

Hi, I'm new to motorcycling, and I am from Eugene, but I saw a bike that I am interested in up north in southern portland (area code 97068).  I don't have enough mechanical experience to trust my own evaluation of a bike, so I am wondering whether anyone can recommend a good shop/mechanic to inspect a motorcycle in that are.  The motorcycle I am looking at is a 1979 honda CX500. 

Thanks


Cold motors - why do they need more fuel?

Richard Johnson asked:
>Why do cold engines need to be richer than warm ones in order to operate?

Martin:
The cold mix vaporizes less and is harder to ignite, so it doesn't burn cleanly. That means less energy (all the way down to doesn't burn at all) is available. At least enough extra fuel must be added to get enough to burn that the engine generates more energy than it consumes in friction. If it is intended that the engine be safely operable, enough extra fuel must be added across the range that the engine achieves reasonable power output.

You folks with belts or shafts can move along, patting yourselves on the back as you go. Emendation to the following text will be carefully considered.

Modern motorcycle chains are generically known as "roller chain". Each pivot between consecutive links consists of two concentric simple machine elements - an oscillating plain bearing and a rotating plain bearing.

The reasonably factual story, I think:

Gasoline degrades for three main reasons (that I know of), with a fourth decisive factor that is not exactly degradation in the sense of the first three:

1. Exposure to UV light
2. Oxidation
3. Evaporation of volatile components and finally,
4. Adsorption of moisture

Thoughts on the fine art of changing your own tires.

Tools.

  • Bead breaker (or make one)
  • 4 tire irons -- the bigger the better
  • some soapy water
  • various scraps of wood
  • some small lead weights (any auto shop)
  • felt-tipped pen.
  • masking tape or scotch tape
