Precision Valve Guide Replacement

Sharing my method of valve guide removal and replacement. This is shown with a Honda CB350K, but the same method is used on most aluminum Japanese or European cylinder heads.

The guides in this video are bronze racing type. The bronze guides waists down slightly when installed with the correct interference fit, and requires a second ream to finish size.

No hammering or heat is used. This method does not damage the guides or requires speed to match the guides heating and sticking in the head during installation.

Any guide installation will require that the valve seats get cut to match the new guides, this video demonstrates my method.
