Check your nylon apex seal oil injector hoses and replace those too Mike.
Those will kill your engine for sure.

Mine were in good shape, still pretty flexible. For reliability reasons I
will probably replace with AN3 hose - I might be removing/relocating the OMP
as well; I plan to inject 2-stroke and not pan oil. Not too hard; the nylon
lines are held on by Oettinger(sp?) clamps that are pretty cheap to get and
easy to use.

FWIW, does anyone know the speed of the OMP shaft relative to the Eshaft?
Might try mounting it where the airpump was, and pulley driving it.

PS - looking at the housings again last night the end housings have pretty
serious stepped wear opposite the intake ports. The intermediate however
looks as if it will spec good when cleaned. Possibly loose bearings, causing
Eshaft wobble under load? Or just high wear? Never seen wear like that on
the torn-apart NA motors.

I think the pump is half speed as I recall. Could be wrong.
Have you seen Richard Sohn's 2 cycle oil adapter for the stock pump?

Not likely on the bearings. Do you have a set of big micrometers?
