Has anyone out there tried the restricter bit with a cotter pin. Some one told me to put the bulbous end of the cotter pin inside the oil return stand pipe in the oil feed tank, then bend the feet around the outside of the tube to hold it in place. He said this will provide a small amount of restriction, and force a little more oil up to the rockers about 25% a little more or less. I have this question, if you put up to 25% more rocker box oil up there, and BSA does not use valve guide seals, would that not cause more frequent spark plug fouling ?? Please anyone respond to this, the more the merrier, all Ideas are good , just some are better than others.
Thanks Much
