[Roadsters] adjusting valves on R16

[Gary and Cindy Ault]

I use Keith's method on my U20.  I set them just a little loose.

Re: [Roadsters] adjusting valves on R16

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
