Fresh pile of crap to overhaul/IRAN.
That front m/c might be toast, but will assess after it comes apart.

Re: '83 GPz750-A1 malarkey.
Arsebiscuits. The difference is in the lower fork legs....
But! I did find EBC 270mm front rotors for $170 each. Haven't bitten that bullet yet
Need to have a major garage tidy up/sort out tomorrow & then finish assembling the carb rack. Found an errant float needle laying on the garage floor this evening.
It had better be from the spare rack (which was laying on the floor with the bowls & floats removed a few days ago). I'll check the spare rack tomorrow. FFS

Re: '83 GPz750-A1 malarkey.
Initial soak in Evaporust didn't seem to be doing the job, so decided to pop the sender unit apart... 
ARRGGHH!!
It's now in the small ultrasonic with water, SG-HD & some Evaporust

Re: '83 GPz750-A1 malarkey.
There'll be some serious weight reduction on that sender unit compared to OE.
There is no cloud, just somebody else's computer.

Re: '83 GPz750-A1 malarkey.
Finished up the carb assembly. There are two very small springs & matching 1/8in ball bearings that hold the choke rod in position. What a fucking faff they were... The hole they fit into is inside the tube the choke rod goes through and then there's faff of the doodads that pull on choke plunger doodads that have a spring, cup & a Ping!FuckIt!
and then throw in the fact that I have 3 different pairs of glasses depending on how close something I want to look at is...
I was starting to question my life choices...

I have separate glasses for close up or just take my specs off.

Re: '83 GPz750-A1 malarkey.
Decided to take some 1200wet/dry & the polisher/buffer to the gas tank to see how it looked... Total waste of time as it has terrible orange peel, scratches, crap quality paint & needs a total strip/repaint anyway.
But I would ride it like this...

Re: '83 GPz750-A1 malarkey.
Did some digging on the Niche website & it appears they have front rotors for the GPz750, but their listing is buggered up. They list the 750 A1-A3 having the same rotors as the E1-E2 (the turbo), but the A has 270mm (10.6in) rotors & the E has 280mm (11in), same as the 1100 A1-A3
But when you punch in the 750 A OEM part # it shows 270mm rotors... & shows them also fitting the 750 E. Gonna have to call them on Monday to make sure they actually have the 750 A rotors...
