Cylinder material identification

Moto Guzzi V700, V7 Special, Ambassador, 850 GT, 850 GT California, Eldorado, and 850 California Police models

There are three different types of cylinders that are commonly found on these bikes. Here is how to identify each:

• Chrome - The material will appear shiny and smooth. Hash marks should not be visible. Absolutely no magnetic pull. Peeling be may evident exposing the bare aluminum below.
• Steel sleeved - A ring where the sleeve was inserted will be clearly visible from both the top and bottom. The material will appear less shiny than chrome. Hash marks may or may not be visible. Very strong magnetic pull - just like placing the magnet on anything else that is steel in your shop.
• Nikasil/Nigusil - The material will appear shiny. Hash marks will most likely be visible. Has a slight magnetic pull; certainly not as strong as steel, but definitely a little pull. If the cylinders were made by Gilardoni (aftermarket only, I think), then the Gilardoni logo will be placed between the bottom two fins at the 6 o'clock position nearest the base gasket (visible from the outside).
