I got a 2015 cf moto zforce 800 with 30" tires it's clocking the mileage as almost double. Is there a way to adjust the mph ? With bigger tires it should be less mileage not more

That's right, it should read slower. Anyway there's a How-To for calibrating the pod in the How To section....somewhere.

there are how to's on the Uforce, have not found anything on the Zforce yet.

Key on, hold both buttons down long enough for a 3-digit number to appear then let go. Change numbers with left button, change digit position with the right. When done hold down both long enough to return to odometer to save. OE setting with 26" tires is 520...I think. Larger tires needs larger number. When I went to 27" I just increased the first number by one and it was close enough.   

As with so many Asia built motorcycles the CF Moto's stock speedometer is somewhat 'ambitious' in its reading how fast I am going. In my case when using my Garmin GPS for true indicated speed, turns out my going up one inch of tire size made for an honest reading on the speedo.
