Just wondering I went by 3 different speed radars the cops had set up around mid Mi. On all of them I set my cruse as close to 50 mph as I could, of the 3 two showed 47 and one was 48.
So with my speedo at 50 I'm really going close to 3 mph slower. So if I go 100 mph would it go to 6 mph slower or would it stay at 3? I'm thinking of going with the PV for my 14 King.

I fixed mine with the PV. And you don't have to mess with the gear ratios, there us a speedo cal.

I need a head pipe,]no cat] air cleaner and turner.
I will call FM this Monday.
Thanks man, you are one of the guys on here I trust. I'm very leery of the PV but I feel with FM backing me up I can make a it work. I had a FM PV-C on my 11 King worked good but I never was nuts about the piggy back deal.

I know that this is an older thread but thought some might find this useful:
From memory:
To get your speedo in sync with the gps try this:
1. speed shown on speedometer / speed on gps = number
2. (number)(pulses per km) = new value
example
1. speedo reads 60
2. gps reads 64
3. 60 / 64 = 0.9375
number = 0.9375
4. current pulses per km = 2300
5. (2300)(0.9375) = 2156
2156 is the new value to enter in the Speedo Calibration
If this doesn't work, do gps / speedo
Been a while since I did this, but it worked.

I know this an old thread but still relevant.
Trying to calibrate my speedo/odo
PV and speedo/odo are off, and I dont think they should be, they use the same data.
Speed is off by 0.61%
But odo is off by 0.78%
On a recent ride my PV trip center mileage did not match the odo mileage.
Am I missing something? I am using the quick tune to change the vss parameters
Thanks
