Title: Valve guide liners.
Post by: trickytree on 12.02. 2011 18:39

Has anyone had these fitted? K-Liners they are called by the Cylinder Head Shop...not sure if other places use/do them?

Cheers, Paul.

I have had them fitted to a head but I am yet to run the engine.

I've used them in car engines but not in a bike.

In the car cylinder heads they are fine, cant fault them in any way.

They are fine on the inlets but can give some grief on the exhaust.
You must over ride the "experts" in the head shop and use BSA's original clearences or there is a good chance that the exhausts will grab.
Most head shops set tollerances for water cooled engines which are way too close for our old bangers.

Thanks guys, I have a set of Black Diamond valves already that the manufacturer recomends bronze guides and pretty tight tollerances. I'll make some calls next week and sort something out.
