<DIV><STRONG><FONT color=#000000 size=3>I have an L crankshaft that has an
exit/entry hole bored into the hollow shaft located just behind the seal
location. On the YS-140 Sport a hole in the same location provides case pressure
to the diaphragm. I don't know it's purpose on the YS-140L, It seems that the
hole was plugged on some of the L model engines. RE: Don Ramsey's post of a
couple of days ago. Don says without the plug he is getting 300 more RPM with
his YS-140.</FONT></STRONG></DIV>
