We appear to be talking about two different ideas here Lozza.
Quote from page 1
"we were interested only in the two-level testing of a
broad concept: would more of a suitable
reference oil cause an engine to produce
more power or less, and would ring sticking
be reduced or made worse?"
I don't see any mention of different jet sizes in the above statement.
My argument is that if you [ I or we ] say to a young rider [ who is keen to learn but has no idea , and don't laugh because we have all been here]
" more oil is better " and forget to mention that you also have to change jet sizes then you [ I or we ] have mislead that young rider by omission and the results that young rider would get may be very different from the expected.
If he/she was for instance to mix up a 10/1 ratio and tip it in his/her tank on standard jetting then I would expect the bike to run hot and seize. [ seen it happen ]
The " more oil is better " statement is bullsh#t without the addition of " but you also have to do this ".
It annoys the sh#t out of me when I hear general statements that are short on facts.
" Seatbelts save lives , in an accident your organs continue to travel forward if you are not wearing a seatbelt , driving through just a couple of cm of water is dangerous , speeding kills , more oil is better ".
