Gauge Swap

[doctorgonzo]

I tried to find a thread to bump on this with no luck.

Do the innards from a lot of models interchange? I'm looking at a Speedo Cluster off a 1979 1000L model. The faces look to be as good or better than mine, and the big bonus, the speedo goes to 140 MPH instead of 85.

I'd rather not swap the whole cluster more thinking of swapping the speeedo/tach guts and faces. Is it generally possible, do most models have the same diameter?

GL model gauges are typically smaller than the regular G parts, at least I know that’s the case for the ‘82/’83 GS850 & GS1100G which share the same gauges. Did you try checking parts numbers to see if the parts interchange? Checking the tach might be easiest since it didn’t change as much as the speedo.

Good idea Ed (operates on the assumption the guy has the right model listed). I'll check the fiche and see if it sheds any light on it. I know the part numbers won't match on the speedo, but I guess you are right, the tach part numbers may match, and that would be a good sign. I asked the guy to get me a diameter, but he hasn't responded yet. I almost hate to canibalize them they are very nice faces, all the lettering (neutral, high beam, etc...) on the bezel is way above average condition.

Way different part numbers. The face on the tach was a separate part in 79. I'll wait on a diameter, and see iof the same. If so I can make it work mopst likely.

Looks like pre-1980 550, 750, bunch of others the same part. The numbers don't match with post 79, even on the tach, but the cluster looks identical. I may risk it on some pre-80 550 gauges sub 50 bucks.
