<DIV><FONT size=2>If leaving it idling for a couple of minutes, then momentarily
flooring the throttle, do you get blue smoke out of the back? That
indicates worn valve stems/guides, possibly rings/bores, the compression test
should indicate which.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV></DIV>
<DIV><FONT size=2>Is there any wet oil in the breather tube from the front
tappet chest cover and the carbs? Particularly at the Y connector and
carbs? If so that does indicate oil is passing that way. You say you
have no oil separator, do you mean you have removed the factory arrangement of
mesh in the front cover? That could well cause it. There were also
two types of cover with different holes and passages, and some have found the
only way to cure oil consumption that way was to change the cover. Also
mounting a catch-tank above the cover port, with the inlet right at the bottom
and the outlet at the top, should allow oil to be trapped but drain back into
the sump at switch-off.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Do you have through-flow with the breather system? There
should be some suction on the hose from the rocker cover to the charcoal
canister. However with no through flow that should in fact stop any oil
passing that way.</FONT></DIV>
