dhdrider,

i believe you have erred slightly. while most (all) manufacturers set their speedo optomistic, it is illegal to set the odometer anything but as accurate as they can reasonably get it. if i recall ahlman's website correctly, the speedo and odo are receiving data pickup from the same sources but they compute values differently; as such, when you enter the correction factor the signal is applied to both the speedo AND odo, which will throw your odometer off as well. i recall seeing a table specifically addressing re-gearing the bike, and you can get either an accurate speedo (odo accumulates slower than actual), an accurate odo (speed reads higher than actual), or a "good compromise" (speed reads slightly higher and odo reads slightly lower than actual).

anyone feel free to correct me if i'm wrong here, as i may well be... but i don't think i am, unless i'm recalling mr ahlman's webiste details incorrectly. i cannot access the website from here to post justification, which is why i'm caveating with the phrase "as i recall". it's been a while since i've been on the site (about 10 months and counting) so like i said, i could be wrong. if so, some one please enlighten me.
