Smokes on throttle off throttle?
Rrings could be up side down. Like that the rings will suck oil out of the
crank case. Work great if you trying to kill mosiktos...

After the usual 17hr drive to my "home" track, I was excited about
the first race of 

the season especially because of the new "big" motor I had. Took it
to the dyno 

last night for break-in and the required new map. The thing was
smoking terribly 

and it was soon apparent that it wasn't just a little extra assembly
lube as during the 

30-45 minutes of run time it burnt at least 1/2 liter of oil. So
what are the possible 

causes of this? It does it mostly while on throttle so that would
indicate rings over 

valve guide seals, yes? I checked the crankcase breather lines and
they are dry, is 

there anything else easy I can look at or is my only choice to start
tearing the thing 

down? Fortunately I did bring down my old motor and got to spend
most of my regular 

sleeping time doing a motor swap :-( I'm guessing either the rings
weren't installed 

correctly, the cylinder bores aren't true, or the bores are too big
for the pistons. I don't 

have the tools to do a leak down test but I did check the
compression and it was 250psi 

in both cylinders, but I guess that doesn't really tell a guy much.
Any advice would be
