well i know 532 to 520 was a big change for me on the r6.. i kept stock gearing because i didn't want to lose any top end and didn't really think the trade off to get minimal acceleration gain was really worth it.. now that i know what's involved in the change and the time it takes i might try -1 in front if i ever feel like fucking with it. I have other shit to do to the bike and I am happy with it for now.
