Odometer trip knob broken

[1.21GW]

Title says it all.  The knob that resets my trip meter stopped working when I tried to reset it at fill up today.  It stopped working as I twisted and then as I wiggled it to get it to catch on something, it pulled out.  I tried to put it back in but it won't lock or latch onto anything inside the hole.

I would normally say, "meh, who cares?" but I use the trip meter to keep track of gas tank levels.

So, suggestions for repairing or replacing?  I'd prefer to fix cheap it but would be open to replace if not too too expensive (is there a stylish sleek odometer?).

The knob itself is replaceable and IIRC is threaded and is only intended to be turned in one direction, but it's been so long since I had a stock gauge I kinda forget.

Thanks, DP.  Looking at the part in the link you posted and comparing to mine, it seems that something internal broke off and is (thoroughly) attached to the knob:

Time for a replacement speedo.

Wrong answer!

Okay, any cool speedos out there?  Something simple.  No tacho needed.

Buy my old m750 speedo? it doesn't have a tacho

Good idea, Howie.  I will look into.

I wonder how it tracks distance?  GPS I guess?  I don't like the fact that it is battery operated (rather than solar or hooked up to the bike), but I'd hope battery life is long.

That was just one model.  Look up CatEye and Sigma cycle computers.  Transplanting the speedometer from Nibor's gtauges into yours would work too.

Most use a magnet attached to a spoke, which passes a sensor fixed to the fork. To calibrate, you measure the distance traveled for one revolution of the wheel and input that into the computer. It computes speed and distance based on the revolutions.

Some can be pretty finicky as far as minimal distances between magnet and sensor. The wireless ones require a battery in the sensor and one in the computer, but they tend to last a while.

I ordered one of these for an ATV, haven't got it yet, so no FHE.  The one that's coming is the Vapor model but they have simpler and cheaper ones.

I've used Trailtech speedos before. Be aware that their warning lights have been noted as being very dim in daylight. They did do a change a few years ago and went from incandescent to LED, but the LEDs they went with were marginally better. I ended up having to install brighter LEDs to replace those.

On the plus side, their speedometer, as verified by GPS, is very accurate.

One other item of note, is that their documentation does not provide instructions for transferring the bike's existing mileage to the display. That may or may not be a problem for an ATV? If it is, PM me and I might be able to help.

Changing an odometer reading is a violation of federal law...even if you're doing it to reflect the actual mileage of a vehicle. Probably why there's no documentation.

Yep. Exactly what I was told when I called them about it.

On an individual state level, some states have a documentation process which legitimizes/documents it. It usually means a new title being issued with words to the effect that the odo was replaced.

HD sells replacement speedo/tach units - if you want a tach for some reason...  and they somehow have a procedure for them to learn the mileage from the old speedometer fwiw.
