When you`ve had the service done, i`d be interested in a pic of you doin 140
i got mine serviced a few weeks back, on opened it up in the week after, i managed to get 135 on the tom tom with the speedo showing about 137 ish
my tomtom 710 shows lower than the speedo @ 70 (on speedo) its showing about 65
i think i could probably get more than 135 as that was on a long sweeping bend M2 toward Gillingham turn off if anyone knows it, know there are a few lads from kent here
