Our Home Page details the valve guides we sell and install here. We became an importer of Intervalves of Switzerland several years ago. They are of similar or better qualty as OEM BMW valves at about half the price. The exhaust valves are stellite-faced. Dealer and independent shop inquiries are invited
We also stock valve seats from Summit Valve. These seats are ground to our specifications, so they fit in the original seat bore without machining. The bores vary a bit, so we have them in a number of sizes. See a samplng of part numbers below. All exhaust seats are $30.00 each.

These valve guides are made to our specifications. The circlip groove on OEM guides has been eliminated and the “clip” made integral to the guide. Made from a special alloy, they resist wear and seizure. Their inside diameter is sized so that only minor honing or reaming is neccesary. Also available for “/2” BMW and Triumph. Dealer and independent shop inquiries are welcome.
