Didn't find an answer searching..

Had a weird problem today. Drove the bike to work, first part of the trip the speedometer was working fine. Pulled away from the first light, and now the speedometer is reading about 40km/hr too low. When stopped, the needle is pointing directly downwards (not zeroed, about an inch below the zero mark). Anyone have any ideas how to fix, and why this would happen all of a sudden?

Only about 5500kms on the bike.

Thanks.

Any ideas???

I had a similar issue a couple of times with the rpm needle. I stoped, switched off the bike, switched on and it was sorted (gauges do something like a self test when you turn on the key switch).

Sorry for the slow reply. Haven't check the forum in a while...too much snow on the ground to think about riding.

I have switched the bike on and off, but the speedometer hasn't sorted itself out. The needle points straight down. Any way to open it up and reset the needle?

When you switch the bike on and off does the needle go all the way to the right before returning back and points down?

 

[CLiVE]

Yes, when I turn the bike on the needle swings all the way up, then returns to the bottom and points down. During normal riding the speedometer still moves, just is about 40kms too low.

Check the speed sensor at the rear wheel for a start... :think::think:

Yes I realize this thread is from 2009, I did a search and this is the only thing I found. I had this exact problem today on my 2006 1000 supersport, does anyone have any idea what could be the cause, I'm at a lose? The speedometer needle is pointed downwards, the odometer is working, the speedometer is reading low because the needle has dropped down.

The needle has come loose from the shaft it rotates on?

Thanks Steveb64

I thought it might have something to do with the computer. I have heard mention of tach needles getting loose on the shaft but not the speedometer, would really like to know for sure before I take the speedometer a part?

It's an electronic speedo? Well, it could still be that the needle has come loose - there's no law saying that it can't happen... - or something could have cooked it's little electronic brain. As suggested earlier in the thread, I'd be looking to try and swap out the speed sensor - or at least check that its plug connections are all clean and dry.

...And these 'speedo-healer' gadgets may be a cheaper (than replacing your speedo) way of sorting your problem out? https://www.cycleworld.com/sport-rider/how-to-fix-calibrate-inaccurate-motorcycle-speedometer
