As an old timer said, a little valve noise is better than no noise.
Good one! Thanks.
Here also some sage advice I learned from another Inmate. To get the feel of the clearance you wish to set during a valve adjustment, set a micrometer at the thickness of the feeler gage you are using. The gage should slide through the valve clearance with the same resistance as the gage through the pre-set mic.
Oh yeah, when a Guzzi is running well, it makes too much valve noise to hear the valve noise.
