GS1000G '81 help identifying parts

[Lorenzo]

Hello to everybody, the parts in questions are: an oval shaped aluminum plate, with a bulb carrying a spade contact, bolted on the camshafts cover, above cylinder 4;



bolted here:




I wonder if it has anything to do with the oil pressure switch, also disconnected:




thanks

No idear, it's certainly not stock. Take it off and shoot more pictures?

Looks to me like the oil pressure switch is connected. Unless you mean somewhere else in the harness.

Your old pressure switch looks connected to me and the other "watchamacallit" is definately not a stock item..throw it out.

The critter has a Veglia 12V and data of fabrication on its side;I checked it for continuity and it has an 1.4 KΩ, at ambient temperature while by warming it up, it decreases to .3 KΩ,

That could be the sensor for an aftermarket temperature gauge of some type - maybe cylinder head temperature gauge? Strange place to mount it, usually the sensor for a CHT gauge mounts under a spark plug against the cylinder head.

Here another picIt is defenetely a temperature sensor, the mounting plate is similar to this, a water temp. meter

Now, what could have been used for? What could I do with it?

Thanks

This is the first time I have seen such a sensor fitted on an air-cooled engine. As someone else pointed out, that sensor was not originally fitted on your bike as standard from Suzuki factory, so you can remove it and it will not affect your bike in any way.

Maybe the previous owner connected a gauge or a fan which was activated from the sensor, because he wanted to blow air over the motor while standing still in heavy traffic and was worried the engine would overheat?
