Wierd Speedo problem.
2002 EG Classic with EFI:
Or maybe not a problem. Pulled out of the driveway yesterday, rode a mile on my street to the main road, everything fine. Pulled onto main road into passing lane. Several cars came over the hill and fell in behind me. Got up to speed and something didn't seem right and I slowed down to let a couple of cars pass. Realized the tach was showing over 3K rpm and speedo was reading 40 MPH. WTH, I was keeping up with traffic. Increased throttle and bike went faster but gauges didn't change. When I slowed down gauges would fall, speed back up and same thing. Didn't want to get into town and break down. Pulled over in a right turn lane and stopped. Gauged dropped to normal. Figured I would shut it off and call AAA if it didn't start back up.
Cranked back up fine so decided to ride on a ways, Damn, everything worked fine. Speedo and tack now correct. Completed my trip town and took the long way home, about 20 miles. No more problems.
Anyone have any ideas what happened.

I don’t have a solution to the problem but I did have a similar “one time” event. On a 30 mile ride I stopped for a break and shut off the bike. After restarting the ride and riding for about a mile I noticed the speedometer was at 0…..as in not moving at all. I pulled over and shut the bike down. After restarting again the speedometer ran fine. And it has never happened again. Also, no codes appeared on the sweep. Go figure?

Not sure if it's the cam but on my 00 FXDX, the gauges will go bananas if the battery voltage gets too high.. It was the sign of a bad voltage regulator in my case. The Tack would lock at 3000 and the speedo would start doing weird crap..

As "88" said.
Pull the speed sensor and clean the metal fuzz off of it.
My 2001 FLHR was doing a similar thing a short while back, and that was the easy & free fix. Only need an Allen wrench and paper towel.

yep... speed sensor... ususally will throw a code tho... then after a couple starts clear itself... mine did same thing year ago and has not happened since... dealer says maybe debris or moisture in the sensor and just a snafu... who knows..

While cleaning the speedometer sensor, clean the connector to it and the connector up in the frame.

I'd be willing to bet I know exactly whats wrong with it. It ain't got no gas in it. All kidding aside, you have loose battery terminal connections. you may thank me later
