I had a cam install, it seems that my speedo is off by 3 or 4 mph. It was 1 or 2 before. Any ideas? My bike is an 09' if that matters.

Thanks

 

what are you using to tune it with? i know the powervision has a speedo offset that you can input to bring your mph more in line with actual.

myself, i know that my speedo reads a couple mph faster than what i am actually traveling. i like it that way. i ignore it, so if my speedo reads 70, and i'm actually doing 67, then i stand a better chance of not getting a ticket.

 

changing cams does not change the gearing of the bike---

the combined gear ratios of the compensator, clutch basket, transmission gears, both drive pulleys and the height of the tire do.

- an electronic device would be needed to re-calibrate the speedo-- most GPS units can give a very good indication of real speed, to determine the offsets

Would this change the miles traveled if the speedo is off by a couple or is the miles traveled calculated differently somehow?

I am using a PCV with auto-tune.

I also had the compensator changed.

 

Adjusting the speedo is easy, you just poke you finger in there and run it around the waist band. Don't get caught wearing them in public. Hope that helps.

 

Dakota Digital makes a unit to recalibrate your speedometer.

Here's a chart from the Mn Hwy Patrol to see how far off you are. Use mile markers and a stop watch, set your cruise at 60 mph.

 

thats too freakin funny

 

Yes they do and it works as long as you don't care if your cruise control or 6th gear indicator light work. Dakota acknowledged the problem! Their answer was don't correct all the error it might work then. (it didn't)
Anyone want to buy a slightly used one? (SOLD)

 

Ok that was funny.. had me going for half a sec.

 

Yeah, I had to read it 3 times to realize he meant FINGER!! LOL!!! I'm slooooow tonight!
