How to "forward" the odometer?

I just bought a speedo off of a parted out bike since mine was shot. The miles are behind on it and I'd like to move them forward (less than 5K more) to be in line with the existing odometer. Anyone know how to do it? Is there something I can stick in a drill and just turn her loose? Or would this take forever?
 
Would take forever...you can pull the speedo apart and there will be a pin that holds the odo gears in place (similar to that of the float pin in the carbs) you'll have to carefully remove that pin with a needle nose pliars and reset the #gears to match that of your existing speedo. Just don't ask......................../.....///// 8-[ and no, only on two of my own that needed the same done, one forward like yours and one backward.
 
try a drill and see how long it takes.... if its deadly slow i would take it apart and do it
 
You can take off the lens to odometers and use a pencil eraser to move the digits forward.
 
It's simple! I can't believe nobody has mentioned this yet! Obviously, you need to go out and buy another GS, attach the speedometer in question and ride until the odo matches the destination GS. :-D Most fun you'll ever have "working" on your bike! \\:D/
 
If you do want to try the drill trick, be aware that the front wheel turns about 775 revolutions per mile. Not sure about the ratio from wheel to speedo cable, but let's guess that it turns about 1000 revs per mile. If your drill turns at 1000 rpm, your speedo will show 60 mph. It will take just over 83 hours (3 1/2 days) to advance it 5000 miles.

So if you use a dremel tool that spins at something closer to 100,000 rpm it will only take 8.3 hrs?
 
If you find a dremel that spins at 100,000 rpm I want one....mine only does 18,000.\\:D/

NO. That would be 100 times faster, not 10.

Even at 10,000 rpm, your speedometer would be trying to show 600 mph. No telling what that's going to do to it. :shock:

At 18,000 rpm it would be trying to show 1060 mph. :oops:

Personally, I would try to get the cable spinning only fast enough to max out the speedo.
On the other hand, if you bend the needle just right, it might read correctly. \\:D/
