KIBBLEWHITE — Valve Guide (Ref. 20-20690M)
OEM style valve guide designed for Vintage/Classic, Touring and Roadster engines. Machined from manganese bronze, this guide offers a softer material that can be easily reamed with an electric or battery drill, then finished cleanly with a ball hone. Its tapered head maximises the contact surface while reducing obstruction of the passages for optimised gas flow without altering the original geometry.
Ideal part for the restoration or maintenance of camshafts and cylinder heads on listed Harley Dyna models. Note: not compatible with RH Sportster. Manufacturer reference: 20-20690M — a robust choice for re-machining guides and restoring a sound base for your valves.
