KIBBLEWHITE Valve Guide – Manufacturer Part No. 20-2131M
Manganese bronze valve guide designed for exhaust application. Precision machining with a shoulder for positive stop and reliable positioning in the cylinder head. Designed to accept camshafts up to 0.600" lift. Made in the USA.
The guides can be easily reamed with a cordless or electric drill, then finish the fit with a quality ball hone to achieve the desired stem clearance. The shoulder aids in alignment during installation and limits axial movement during reassembly. Replacement part suitable for vintage and roadster engines, particularly common on certain Harley-Davidson Sportsters (e.g. XL 1200 S, XL 1200 C, XLH 883 from 2003), however, check the dimensions before installation.
