Removing the head shims
Hi,
I'm running the K5 for almost 17 liters now and the engine still runs strong and is really, really easy to tune.
Last week I read through the manual and found that a head shim should be removed after running in. Somehow I ignored this till last week. Then I change the shims as recommended in the manual and this makes quite some difference. The engine does now accelerate quicker and feels even stronger.
