Barking mad? No, not at all Dave, but remember the auto-lube is designed specifically for road use and engine longevity.

A manufacturer is going to run the safest variables possible to try and ensure the motor performs well in all conditions, which does not necessarily mean you will get peak performance. Also, a street rider will put the motor under all sorts of strange conditions that, strangely enough, a race bike will probably ever see. Full throttle when luke-warm for example, or long periods of closed throttle.

Take a UK spec' RGV as an example. Just because the UK market bikes were sold as "full power", would you not consider optimising the systems still further or just race it "as-is"? I've seen UK spec' RGV's (well run in) ranging from mid 50's to low 60's in horsepower.

There is an optimum fuel:oil ratio, and it doesn't need to be variable on a racer... it just needs to give peak performance.

Like I say, the subject can be argued 'til we're all blue in the face, but I don't personally think for riders of our ability (no offence to anyone, but if we were that good, we'd be riding GP!) it's not really going to make any difference whether the pump is used or not!

You are as entitled to your opinion as the rest of us though, and far be it from me to say otherwise!! ;)
