I am looking for the wire diagram for a 1984 gpz 900r

Take off wheel...remove cush drive on sprocket side...prise the oil seal out on the brake side and you'll see a circlip...remove this and drift bearings out. Drift new ones in with a socket or bit of tubing that is the same size as the bearing outer so as not to damage the bearings...re-fit circlip.

capped off the system on my gpz1100e with no wet or winter problems...
just as likely to get carb icing on my 900r which has an intact system with new filters...so I wouldn't worry.
new filters are cheap enough though if you want to keep the system...

Cool bike!, The seat latch is a bar with two hooks that runs across under the seat, you may be able to lever it forward by removing the right sidecover and probing with a long flatblade screwdriver.
From memory ,the latch is actuated with a cable from the lock that has probably broken or siezed.
Sorry, it's been a couple of years since I sold mine.

I guess you mean a 750, The compliance plate should be on the steering head, right at the front between the upper and lower bearings. That is where it is on my 1984 900r and they are almost the same bike.

try using 0.14 -0.15 mm

Yes only the A1's were difrant A2-A9 the motor's never realy changed A7 had a better chamchain tensioner but from A2 the motor never realy changed Note the is for ZX/GPZ900R motors and not ZX9R's

No but there is not much between them if i remeber right the cam lobes are slightly bigger which would give you more air and fuel which maybe be detrimental. check cam lobe sizes in the haynes manual for 900 and 1000 and compare

their either carb vent lines or fuel lines if vent lines the go under the tank if the are fuel lines they go to the petcock
