2009 r1200gs valve check- feeler gauge resistance?

[oldjoebmwrider]

In checking the valves on this model bike, how tight or loose should the valves be? Should the feeler gauge move freely or be snug and difficult to move. When I checked my bike the feeler gauge was pretty tight and difficult to move.

Thanks,
Joe

Use 3 feelers. 1 the size of the desired gap. One a step thicker, and one a step thinner. It's called no-go-no.

First set the gap using the one that is the desired gap. Then try inserting the thicker one - it should take some effort. Then try inserting the thinner one - it should slide through easily with almost no drag. That is then close enough..

After you get a feel for the amount of drag that's normal you can skip the thicker and thinner.

One important point - when doing the measurement the other valve on the rocker arm should have a feeler of the expected thickness in it. That keeps the arm parallel to the valve stem.

Good idea, I will definitely try this ! Thanks Don !

Hi Joe, I added a bit to your title- " valve check- feeler gauge resistance?".
This should attract some additional attention to your question.
Let us know how you make out.

I use the 4 gauge method and a slight drag in resistance. It is a dance because loosening/tightening one changes the others though you would not think it would.

For your amusement you can make this rocket science.

You are NOT better than a pro, and pros don't.
