Speedo issue

2000 ultra classic
Every now and again, the speedo will read between 20-30 mph slower than I am actually going. If I stop and shut off the bike and start again, it works fine. Anyone have any ideas?

Pull your Transmission Speed Sensor out and see if the magnetized part of it hasn't accumulated some metal fuzz on it throwing the sensor off. Wipe it clean if it's dirty and see if that helps. If it's not too bad, or fails again, it may just be time to change it out cause they get old and fail. $58 on Ronnie's. May be cheaper elsewhere, but that's the site I pulled up. That's what happened on my 2003 RK and all is good now.

Thanks, brother.
This happens maybe 1 time, then few weeks later maybe will do it again.
This is what I thought it might be, the sensor, but looking for verification, before I
started chasing.

I had this on my 05 Glide when new. New sensor(s), dealer got frustrated and replaced the speedo. Neither was the problem. I caught it by accident when I was removing the inner fairing for paint. There was a loose ground on the triple tree. Took care of that and haven't had a problem since.

Looks like your dealer needs a better trouble shooting technician.

Your win. Shame you can't keep old parts and even worse that speedos marry to the bike.

II have experienced similar on my 02 EGS. I discovered that if I turn the ignition on and the run/off switch is already in run position and I start it up, the mph is off like 10mph. So...I check my switch positions before turning the ignition on and starting. Normally I use the ignition switch to shut the bike down, so the run switch is almost always set to run. You’d think I’d learn by now...switch it to ”off” before dismount.
