Re: Autolite 3923

I don't think you need to change plugs because the wore our anymore.  
In the car, if you try to go 100k on the same plug, you may not be able 
to get the thing out without doing damage.  I change at 50k before they 
get corroded in place.  Seems to work.

One other comment on the valve adjusting thread.  Someone mentioned the 
valve clatter.  Most of the valve clatter is not from the valve 
adjustment, but rather from the end gap adjustment.  This is covered on 
the IBMWR site, and probably in OVAD also.  Setting this gap carefully 
really quiets the motor down a bunch.

Lots of good info in the last few days. Looks like riding season is 
ending for many of us.  Let's see how long we can stay civil before the 
winter blues set in ;-))
