Changing clocks on a GS250TT

[rwms71]

I have a 1980 GS250TT (the custom model) which only has a neutral position light on the instrument cluster. I know that the 400/450 models do have a gear position indicator and was wondering if it is possible to replace the clocks and the wiring in the gearbox. I am told this bike is essentially the same as the GSX250?? but not sure if any of these have GPI's

Would also like a fuel gauge to, but that looks like too much work to install a sender in the tank...

Any advice on which models come with it and if it is possible.

Thanks Rich

Hi Rich, the only way you'd get a gear position indicator on there that I'm aware of is if the end of the gear shift drum has a pin set up for this already.

The gear position sensor is basically a disc setup that has contacts for each position including neutral which is grounded by a spring loaded pin on the end of the drum. This mounts over the end of the gear shift drum behind the sprocket cover.

It's installed at the top there:



And you can see the hole for the spring loaded pin here as well as the mounting holes for the disc:
