VALVE GUIDE SET Norton 750 .006 over Commando guides

This is a brand new set of 4 Bronze guides for your 750 Norton Commando. These are made in the USA. This set is a .006 over size, we have standard, .006, .004, and .006 available in our ebay store. Non standard sizes are available.

These guides are Phosphor Bronze which is the best material to use for guides on these Classic Bikes. Silicon Bronze which is the next grade up tends to wear out the valve neck so we stay away from it. With these bikes the Phosphor Bronze offers better lubrication and they live better in the aluminum heads." There are many opinions on this subject but this is our information after 30 years of testing in many different environments, and conditions. Our tolerance on these guides is tighter and more accurate than many of the other leading suppliers, (the hole is closest to center than any other guide available)
