i found my battery drain in the heated grip fuse circuit and pulled that fuse. the battery has been great since but the speedo only works half the time. it shows zero or works. if i restart it might work. 2004 rs. hasn't anyone experienced this? j

Hasn't happened to me but I only have around 12,000kms on it so far.

Jellero,

Did you check the wires on the back of the speedo and the plug? Does the odometer keep track of mileage?

You're not the only one. My '02 Sprint has the same problem. Roughly 50% of the time I start the bike, wait for it to warm up and ride away with the speedo showing 0 (zero). I can stop and switch off at the end of my driveway and when I restart the speedo works fine (90% of the time anyway).

If you find the source of your problem I'd love to hear about it.

Cheers,
Steve

There is a fix for this. I am just living with it for now. I changed my start up procedure. I no longer wait for the fuel pump to prime and for the dash to clear. The computer goes through a check system every time you turn on the key. One of the checks is a Spedo error check. If your battery is not in new to almost new condition the error check disables the spedo function for some reason.
My 'new' startup procedure is to turn on the key and hit the starter as fast as I can. This seems to start the bike before the spedo check function and once the alternator is on line it seems to fool the computer into thinking the battery is at the voltage requirement to not disable the spedo function. This works almost every time. If it doesn't just wait about 15 seconds for the RPM's to settle into the warm up rpm and restart, has worked every time for the last 6 months.

The fix is to get a Tune Boy and disable the 'Spedo check function. Thats one way.

The second way is to get your dealer to upload a newer tune that will also disable the check spedo error function.

Third would be to get a new battery so the voltage is in the range to not trigger the error code.

I just haven't made the time for one of the first two options.

i took mine to the dealer and they said the sender unit was bad and replaced it. that dealer doesn't seem to know what they are doing though. bike won't start not after they worked on it. speedo worked while pushing it. j

Thanks for all this info Stlakid. Much appreciated. I'll try your startup procedure and if it works I'll try one of the other fixes. I assume there are good reasons for the check system so I wouldn't want to be bypassing it on a regular basis. Sounds like a new battery is in order.
Cheers,
Steve

A lot of people got sold new speedo sensors. Some have been known to fail, but most are just this computer glitch. When I replace my tires I put some new grease on the sender while I have it apart. There isn't much to go wrong with the sender if it doesn't self destruct, just a couple of magnets and a sensor. And you need to be careful putting the front wheel back on so the notches line up. That could do damage if not lined up correctly when everything is bolted up. I would see if your dealer has an upgraded tune for your bike first that will cure the problem regardless of your battery condition.
My battery is going on three years old. Probably good life for a motorcycle, but it cranks the bike just fine even if it's not in new condition. Your probably right though, I bet within 6 months it goes belly up!
