Solid Valve Guide Seal - KIBBLEWHITE (manufacturer part no. 71002-4) is a solid replacement solution for the valve guides of vintage engines. Machined from filled PTFE, this seal retains its mechanical properties up to 500 °F (≈260 °C) and features additives to stabilise the material and reduce friction between the stem and the guide. Its design incorporates a dual spring that ensures continuous tension on the valve stem, limiting sealing losses and premature wear.
Designed for Shovelhead-type cylinder heads and other classic engines, this solid valve guide seal is aimed at riders seeking reliable sealing between the stem and the guide without altering the original geometry. Ideal for restoration or periodic maintenance, it offers a durable solution to limit oil ingress and preserve engine responsiveness.
