My brother had a Kawasaki 185 Enduro once. It had an oil reservoir and an
auto-oiler system for lubing the fuel for the 2-stroke. One day we were
riding and he was really excited! "Wow! The bike's going REALLY fast
today! I wonder why?" About 5 minutes later the motor seized up ...the
tube from the auto-oiler had fallen off. So yeah, running short on oil
gives you extra power ...for awhile. Race motors are pretty well abused
anyway, so making them temporarily 'do' with a little less oil for a race
wouldn't surprise me, especially in the class races where the motors all
have the same displacement and/or the races are shorter.

Thanks to all for the info. I will leave as-is for now, then add the
nitrous injection when I mount the supercharger...;-)

I got the changing the mix for added boost bit from motorcycles. Some
(amateur) racers I know cut down on the oil during time trials and
races to boost performance. I think it's only a couple of percent,
though. Could be yet another myth?

Hey, speaking of myths, maybe I'll try the cow-magnets, the Pro-lube
additive, Marvel Mystery Oil... or maybe I'll just go on a diet to
improve the weightower ratio!

Ah, who needs to plane a dink anyway?
