so I'm riding to work the other day I when I get to the 25 mph section I look down and low and behold my speedo is deader than a 3 legged armadillo.

any suggestions? its an electrical wire not a cable that runs down to the wheel right?
cause I originally thought the cable had broken.

Is there a fuse or something simple I'm missing?

any one offer any ideas?

Dont know about the ST but the RS suffered from a dead speedo when the battery was not charged or faulty. Speedo was linked to the ECU ..

I thought of that, cause I hadn't ridden in a while and was riding with my heated grips and electric jacket on....
guess I could throw it on the charger and see

battery is a few years old and all.

Have you tried it again since then? My speedo died just the other night, but after the bike cooled down for awhile it came right back up...

 

[REGULATOR]

put the battery on the charger for a few hours.... back in the bike and speedo is still dead, odo as well...

any body ever have one disconnected at the panel?

I'm thinking about popping the front wheel off and checking the sensor..... might have to remove some body work and make sure the connections is good at the panel as well

Update, removed the front wheel, was pretty cruddy near the speedo sensor thing.

cleaned it all up straightened the tabs that hold it in place and lubed the sensor magnet spinning thing ( technical term is?)

for those of you playing at home that haven't had your front wheel off, there is a housing that holds a metal cylander and that has a round magnet with two slots. it appears that the magnet spins around the cylinder when the wheel spins, the wheel has two metal tabs that engage the magnent and cause it to spin when the wheel does...

if anyone cares I'll take a photo,,, not too many miles on the bike but this baby is dragging bad.. might just replace it anyway depending on cost,

Reg,

FWIW, I've read somewhere else on here that the speedo fault may be in the "map".

You might want to try and schmoooze your local dealer into reloading whatever map you're running.

Seems like someone suggested trying to start the bike before it finishes it's wake-up. You might try searching for that thread.

Or, go spend $40 and put a Sigma bicycle computer on the bike. It's more accurate, too.

HTH, Steve

I read all of that and was really hoping a simple retune or refresh would help, but once I got te wheel off and realized it was'nt turning freely ( the speedo sensor internals) I knew it was just gummed up somehow.

so a good cleaning and overnight soaking, and if it works I'll get back to evryone.

although now that I have the bike supported and teh front wheel off, I think its a good time to replace my fork oil!

off to search on that topic again

The speedo on my bike died when my friend still owned it.
He had been out in some heavy rain fall,He told me that first it went totally dead then it started working again for a couple of days.
It had gotten water inside it somehow and shorted something out on the circuit board.
The tachometer was still working and all the warning lights.
Sadly my bike had only 8k on it but with a dead speedo it's going to be impossible to show.
Now I have another speedo that works fine but it reads 17k
and it's in Km not miles so that sucked big time.
Maybe the contact has got a bad connection where it goes in on the back of the housing,
Mikey

Problem solved, I removed the front wheel, cleaned up the goop inside the speedo section, then rebent the tabs that are in the wheel.
I also popped off the fork tubes and drained them and put in fresh oil while I was at it... gonna take me a while to get the front end adjusted now but speedo works and all is well in the world again.

That's great news and thanks for letting us know the result.

I went for a ride in the mountains Sunday for a few hours. When I got back at the first light the tack went to 0 and then to max revs, all the lights came on, but it ran fine. Thought it was just one of those things and it did it at the next 3 lights. I only have 1200 miles on an 06. Of course now that I am back in town it does not do it at all. Any ideas?

The spedo thing is a glitch in the early tunes. You can have the latest tune loaded and it will stop. When the battery voltage drops (as they do when they age) the speedo will stop working. Next time you start the bike 'DO NOT WAIT FOR THE FUEL PUMP TO PRIME OR FOR THE GAUGES TO SETTLE INTO A NORMAL STATE' The ECU looks for the proper voltage during this time and will disable the speedo if your battery is not in near new condition. Next time you start the bike just turn on the key and start it as fast as you can. This has worked for me for over a year now. I did need to replace the battery this past week and the problem no longer exists. (at least for the next year or so!)

This does not apply to the new 1050 engines.

my speedo issue was a direct result of the heavy handed guy that changed the front tire and may have stuck the speedo unit on and bent the tabs that spin it in a little bit.

I say this cause I changed the front wheel myself and the more I think about it I had no clue that it wasn't lined up wth the wheel bearing tabs when I installed it. so lessoned learned for me, costed me nothing but time this time
