Suzuki 2 Strokes

OK this is a 4 stroke question but I think its relevant to two strokes.
a couple of guys on the ER6F forum recon that going up 1 tooth at the front and 2 at the rear will improve acceleration etc etc.
I thought that by going up 1 tooth at the front is equivalent as going 2 teeth at the rear but 1 into two I honestly can't see the point.
can some one enlighten me?

Unless i have my wires crossed you would want to go down on the front and up in the back to make it quicker but then the flip you may run out of RPM's limiting top speed ?

yes that's my point.
I told them by going down one tooth is equivalent of going up two teeth.
but they said the opposite. 1 up and 2 up the back???
even if it was 1 down and 2 up at the rear that would be a bad gearing I'd have thought, you'll run out of puff in no time and probably be lucky if you can do a ton!
on my other bike I went up on the front to get the revs down.
got it down from say 5500 @ 70mph to 4500 @70mph and improve economy at the same time.
the ER6F is not a particularly fast bike but fast enough for me.
top speed is 127/130mph,50/60 mpg UK imp gal.

Gearing is usually around 3:1 so 1 on the front would need three on the back to stay at more or less the same gearing.

That would slightly raise gearing and would reduce acceleration.

QED, someone got their wires crossed.

Unless the bike is under-geared already and works better by raising the gearing to let it pull hard at lower revs.
