It's hard to get the speed here at altitude.
My 02 we did a couple runs on a deserted road near Four Corners and got 176.4 gps on the limiter. Still close to 5000 ft altitude there.
For reference, mine has 30K miles, Hindle exhaust (not the step tube), BMC filters, PCIIIUSB, -1/+1 on a 190/50 tire.
I've seen 181 with the same gearing and a 190/55 tire.
One day I plan to set up my 2000 model for top end... just too many other projects right now.
