Speedo Healer
I bought a speedohealer for my hawk, read alot that they show way to mouch on the clock. Installation wass easy took only 2 mins, but my question is, any one know how mouch the original speedometer show to mouch 8-9-10% ?
I know the right thing to do is to dyno run it, but aint one arround atm.
Thx.

I just used a GPS and speedohealer's online calculator to figure mine out. (I also did a sprocket swap, so I can't tell you what the OEM part of that was)

ride with a person with a known good speedometer (or follow a buddy's car), reset your trip meters to zero ahead of time. Ride a good 20 miles or so, then compare odometers. If your's reads 22 and your friend's reads 20, you are off by +10. IIRC, you would set the speedo healer to -(1-(20/22)) ~ -9.1%. Anyone?
Do another run afterwards to verify. JB

My Garmin attached to the tank via suction cup showed I was off 10%. I checked every 10 mph from 30 on up to 100. So when the Hawk showed 60 I was actually going 54 according to the GPS. Every reading indicated almost exactly 10 %. Hope this helps

Math is a funny thing. If your Garmin showed 54 mph and your speedometer showed 60mph, your speedometer is +11.1%, to get it right you must reduce it by -10.0%.
OK Tweety - what did I do wrong here
54x=60
x=60/54
x=1.11
60x=54
x=54/60
x=.90

I see where you are coming from. I am a teacher and understand those numbers, but not a math teacher. I was more interested in the estimation thing. More the Life Science type. I only care enough to keep myself from getting a ticket. I just needed to know how much over the indicated I could go and not get bothered by the LLEO.

Nothing wrong with your math...

EDIT: Only caveat is that doesn't look to be sealed from weather, which is bad... It is, so no problem...

Problem solved. Had it on a dyno run last friday. speedo wass 7,1% off what my speedo showed, so now it shows the right speed all the time
Also had it tested with hp and max speed.
115hp on back wheel
255 km top speed.
Gonna change the rear spocket now -2 teeth down, should be arround 275-285 top speed then, but time will show.
