Speedo off about 4 MPH

Postby tech1 » Sun Aug 21, 2011 9:38 pm



Hi everyone
I have an 86 SEi and my GPS shows my speedo off about 4 mph at 55. It is slow I am going 55 when my speedo reads 59.
I have the correct tire size on . I purchased my bike use and was wondering if the cluster could have been repalced AND if all the Wings used the same sized tires. And if there is a way to correct the calibration.
Thanks for any help and info.
Joe

Very common to a lot of bike brands. Probably nothing you can really do beyond making a mental adjustment. My 1500 speedo is bang on with my GPS, my Kawasaki out about 8%. My buddies 1800 is alos out about 8% but the other way.

Until now I have never heard of another Goldwing that had a speedometer that was right on. Most are 3 to 5 mph off at any speed. Not much you can do about it. My 1500 is also spot on at any speed. Makes you wonder what's up.

My 1800 under reads by about 10%, It shows 60mph when I am doing 55mph.. You can fit a speedo healer to correct it if your speedo is electronic, cable ones really cant be fixed. Apart from the fact that it causes me to change oil 10% too early and means the bike shows a higher mileage than it has really done, I like the added safety margin it gives me.. I usually ride 5mph over the limit, that means on the wing I think I am speeding but i'm not, so no speeding tickets!! It's all in my head.. :)

Hi Gary
What is a speedo healer? I have never heard of anything like that.

Hi Joe,

speedo healer is just a generic term for an electronic box that is connected between the speedometer pick up on the front wheel and the speedo on the motorcycle. It modifies the signal from the speedometer pickup to make the speedo show the correct speed.

There are many different ones available, but this is one site that sells them:-

http://www.speedohealer.com

You can find many others and maybe someone will recommend one? I used one on my 200 Yamaha R1 and it worked brilliantly, took 15 minutes to fit on the R1.

My '83 1100A has the digital dash and it reads about 4 MPH high too. Seems to be normal for these bikes I'm afraid.
