Hi Paul and Y'all
I have been thinking about the lubrication problem for the apex seals
for some time now. I like Richard Sohn's idea with the metering pump
but do not like the dilution/contamination of the engine oil with 2
stroke oil and the subsequent rise in oil level. The factory idea of
using sump oil puts most of us off, why I am not sure, all the crap
gets caught in the filter, but there it is. So, when i was a 'youngan'
, I used  castor oil in bikes because it was a good 2 stroke lubricant
that would tolerate high temps, (upper cyl), and would burn clean and
leave no residue. Castor oil in Richard Sohn's tank or just a mix, as I
will do, may be a good alternative to sump oil lubrication of the apex
seals. A side benefit is that although the noise level will not change,
it sure will smell nice! BR, Dave McC

Get thee to a case of Idemitsu rotary engine oil.
You can burn that from the oil pan.
