I am hoping that someone in here can tell me what the part in the pictures is.

where is it located on the bike? Do you have an pictures a little farther out. Could it be a temp sensor?
It was originally located inside of the front inner fairing on the left side up near the headlight. And, I guess that it could be a temp sensor, but I have no idea why the temperature inside the fairing would be monitored.

Actually, I take that back, I think that it may have been closer to the turn signal than the headlight, but still in place that I can see no reason to monitor the temperature. It looks a lot to me like the mass air flow sensor typically found inside the intake ducting for a fuel injected car(toyota).

an 87 is too old for air temp sensors.... we need some pics farther out of where this came from because ive checked the parts diagrams and i cant figure out where this part is from

It is an air temp sensor....... don't have the wiring diagrams here to give ya, but pretty sure that what you have there.

edit: found a diagram for ya, and can see the wires, but can't read the labels well- too low res.

If its too low res to make your point dont stick your foot in your mouth... Think logically, in 87 even cars still had carbs, there was no reason to have temp sensors. The only item on there that has two blueish looking wires is a diode for the rear tail light. Like i said, not a temp sensor, dont judge a book by its cover.

Seeing as its a fixed unit with what looks like a plunger switch i want to say it's a redundancy switch like having to pull the clutch in to start the bike, something must actuate the switch. That's a guess but the title excludes me from guessing so I'll just throw my thought in the pot and leave.

As I stated in the previous posts, it was located on the left side of the bike on the inner fairing. Not really near anything that it would really make sense to be sensing a temperature. It is not some sort of plunger and it has no visibly moving parts. having been thinking about it more and taking into consideration some of the possible suggestions that have been given, I'm sort of inclined to think that it might have originally been a temperature sensor for monitoring the ambient air temperature for some aspect of the california emissions controls that were originally installed on the bike. Or possibly it might even be an air flow sensor that maybe opened a valve that would allow the charcoal canister to be purged once the bike was traveling at some minimum speed. Although neither of those theories are really very convincing to me, I am still open to anyone that knows for certain. If picture is too big then zoom out because I have no way to recreate it in it's original location. I do not think it has ever been connected since I have owned the bike, and I was really just curious about it's purpose more than having a genuine need to reinstall it.

And the wires went to nothing?

The only thing with dual blue tracers in that schematic is the front brake diode.

The 84/85 GPZ750 had an Air Temp Sensor.

Side Point: Most cars/Trucks (especially Ford) had switched to Fuel Injection by 1986. I think Honda carried the carb banner a little further, but I know Ford was done with carbs by then.

By the time I found it the wires were no longer connected to anything, and I have not had the time or energy to attempt to locate where they may have potentially been connected originally, and even if I was to successfully locate them chances are that they just end up being bundled up with a bunch of other wires wrapped in electrical tape in the wiring harness and tracing them would be therefor a monumental chore.

I could be wrong but my first thought was that it was a relay for the blinkers.

i looked at all of the micro-fische documents at cycle-parts.com for your bike, but struck out on finding something that looks like that. Does the shaft rotate or does it push in and out? Sorta looks like a limit switch of some sort to me.

No moving parts at all.
