[Roadsters] adjusting valves on R16

[Gordon Glasgow]

You can also get stepped feeler gauges where the first inch or so of the
gauge is one thickness and then it jumps up .002".

Rather than using a .017 feeler gauge and judging the feel I use a .016 and
a .018. The .018 will not go in, the .016 does and you are good to go. If
you  want to do cold setting then set your engine warm then let it cool
overnight and  remeasure. That is your engine's cold settings. 
 
The problem I had before my engine rebuild was that the valve adjustment
changed a lot. Set it one time good, check a few days later and they were
all  over the place. Turned out to be bad lobes on the cam. Six of the eight
were  damaged so as the lifters rotated the clearance changed. What I did
was reset as  I found tight ones and left loose ones alone. That way they
varied from correct  to loose but never tight. Didn't hurt performance too
much. I was slowing down  after trying to keep up with something a bit
sportier and got a speeding ticked  at 95 mph. (not reccomended)

If you  have NO idea what your valve setting is (R16) - safe is to set them
at
20  COLD - warm up the engine and then set to .17 HOT.Good test on accuracy
 -
if a .18 fits then you are too loose.Don't also forget to press down on  the
push rod side before adjusting (just to make sure there is no oil in  the
cup)
And HOT is (as far as I know) the ONLY way to set them. Engine is  typically
HOT after a short run to the liquour store, so you can acquire  what is
needed for PATIENCE <G>
