I just got a 2018 cforce 500s only had 30 miles on it the mph is way off full throttle is showing 110 mph...I went to the calibration setting on atv it has 3 numbers 336 any idea for number calibration....it has the factory rims and tires there 25inch tires I've called my local dealer and reached out to cf and nothing

When I do it it just shows 3 digits spots...and no decimals

That's normal. Start with the first number, the 3. Take it to 1 then using a GPS or someone driving beside you check the calibration at about 30mph. If it's closer but not enough lower the second number, the next 3 to 1. That may be too much and if so take it up to 2. Fine tune it with the third number...either up or down to where it is the same as the reference source most of the time. Remember when change these numbers you must save your changes by holding both buttons down until the cluster returns to normal. Otherwise it just defaults back to what it was. Good luck...but it does sound like you may also have a problem with the speed sensor or the pod itself if it's off that much.

Ok thanks I'll try that way just now cf moto responded to me they told me to try 735.

Try it..of course. I can say when I put larger tires on mine it slowed the drive train..showed 25 when I was doing 30.. so I needed to raise the number to increase the the speed. Yours shows very fast already so that's why I suggested dropping numbers. But maybe the newer ones do it differently then the old ones. Either way...you'll get it.

Thanks I'll keep you updated
