So I pick up an '84 VF750F that was close, and the right price. The PO says it ran, but had a low speed misfire. I can work with that I reckon.

She's a little rough around the edges, but that's what a project is right?
While I wait for a new battery I decided to open the carbs to see what condition they were in. Obligatory before shot:

Anyway, when I opened them up, they were bone dry, and only had a slight film of filtered rust. Pulled the jets and they were fine too, so I pulled the rack apart and gave them a going over with the glass-bead blaster after taping them all up. I'll replace the caps later.
and after, fitted up again:

I gotta say I was expecting all sorts of hassle removing and installing these, but in the end it was all quite painless. I've had more trouble with the CB900 and the airbox issue. I did have to remove them once to re-fit the throttle cables tho. Won't make that mistake again.
So I turn my attention to the fuel pump. I hooked up a temporary petrol supply and found the connector to the pump and ran some wires to the battery. Got my squirt of fuel, so I figure the pump is OK. Reconnect the connector, and turn on the ignition. Now the battery that came with the bike has just about had it, but I thought it would be ok to do some circuit tests. The pump worked when wired directly, so I think there's enough juice. It won't crank the motor, but I'm not ready for that yet anyway. I was expecting the pump to kick in and fill the carbs, but nothing happened, so I'm wondering what triggers the fuel pump?
I think A in this pic is the pump relay?

and is B the main relay? They both seem to be getting power with ignition. In fact all the static electrics are working (lights/indicators etc). While I'm in question-asking mode, what is the "tail light" idiot light indicating? It lights initially, the fades out after a second or 2.
