Trailtech settings

Allright I just got done doing countless searches here for the correct circumfrence numbers to punch into my panoram. I know I saw it in a post somewere. Does anyone know what it should be set at. Right now I have mine at 2154 but I have a feeling that I am off a bit. Anyone have numbers a little closer. Its on a 99 yz400 should be the same size as any other bike here. HELP!!

let me look at mine tonite or tommora and i wool post it!

what brand and size tire do you have 21"x?x?

Im runnin a Dunlop D756 80/100x21. Thanks for the help.

The best way to measure the milimeters for the trailtech and all bike computers is to dab a knobby with water or other, sit on the bike, roll forward on concrete one revolution, measure the the distance between the wet spots (no comment on taints needed or required) and program that number into the trailtech. I did that and it matches exact when tested over a great distance with my gps. Max speed, ride distance, total distance, avg speed it all matched the gps. Good luck.
