I believe they were still using my speedo in 2002. If so, yes, you can calibrate it for speed accuracy. Take a look at these instructions.
Thanks for sharing this Rick. Don’t think I’ve ever seen this before. Do you have this little black unit on your speedometer? Is this what is referred to as the Electronic Control Box in diagram #3?

Huh, no I don’t have that. My speedo is 100% self-contained and is easily calibratable per these instructions. It was amazing to discover it after 20 years of speed calculations in my head. The first 15 I was going 10% faster than the reading and the next five years after replacement I was going 10% slower than the reading. The five years was the toughest after 15 of opposite issue. I would find myself creeping into towns where the speed limit dropped to 45 or 35 if I did it subconsciously. Calibrating it to exact was a liberating experience! It sure messed with my odometer tracking of fuel too.
Is that perhaps the brain of your sensor? Do you have a transmission sensor or cam sensor? Mine is tranny. And that black wire bundle hard wires to it on mine. No nifty disconnect.

I am having trouble with my OEM speedo on a 2005 bigdog mastiff. Originally it would test up to around 20 and then to zero. The tach would work but the needle would bounce around 10-15 mph while im on the highway. The odometer seems to only be tracking mileage at that MPH as well as because i rode probably 18 miles and the odometer only tracked like 3.8 miles.
Any i thought Speed sensor.. I ordered and installed the new speed sensor from Wildsteed and it didnt fix the issue. I tried to "calibrate" with the 2 mile distance procedure, thinking that would fix it. I only got Err on the screen 3 times in a row.
I likely need to start tracking wires etc.. but don't want to take the tank all the way off if i dont have to. My mastiff has a "dashboard" type thing with the speedo installed in it. I noticed in a picture somebody was using that looked like it may have been yours, you were able to get that middle dashboard off without removing the tank.
When i pull up on mine it comes up a little but then i feel some resistance and certainly dont want to break it. How did you get that off, just keep lifting or are there some set screws someplace?
Look forward to hearing back from ya as getting the dog back on the road has been a challenge from changing the start to now this.
Bike runs good and if it was just the speedo id say phuk it and just ride, but without a gas gauge the odometer is critical so i dont end up pushin it.
Thanks in advance

mine is a 2005 and has no visible hardware.. I can lift the edge closet to the seat but there is clearly something retaining that top portion by the bars, just cant see whats holding it

Could there be a screw from under the tank though the frame? Not sure.

Yea i think i have reserved myself to just taking the tank off and giving myself all the room i need to work without tryin to be slick and making a bad situation worse. The only screws under the tank i can see is the large hex head that goes thru the frame. Once i get it all off i can see whats up.
I just hate "figuring it out" and then finding out from somebody else, you didn't need to do half that shit that ruined your Sunday garage time to get the job done. But that's the way you learn, so I can help the next guy out who has a bike like mine

Im thinking there is likely a small hexhead that isnt able to be seen until the tank is either loosed and pulled back or removed completely. Right where the backbone necks-up to the handlebar area. At least the thought!

The 05 dash is a little different. There are two allen screws under the front. Take them out. The rear is held down by a pin. Gently push down on the rear of the dash and push forward. It will pop off.Im thinking there is likely a small hexhead that isnt able to be seen until the tank is either loosed and pulled back or removed completely.

MLeach72 was exactly right!
My 2005 Mastiff has a speedo in the tank (dashboard)in order to get that center section out of the there you will need to remove two hidden allen head screws that are mounted in the very front part of the gas tank underneath. The pictures are taken looking under the tank with a mirror. Something tells me these are gonna be great fun to get back in. BUT will get er done.
Thanks Again MLeach72 as i hadnt found any clips that showed how to get that piece out.

Is your rear pin missing? You shouldn't be able to lift up the rear of the dash. There should be a bracket under the rear dash with a grommet in it. It slides over the pin.
