Well first job today was taking the wheels off the CB750A so I can finally get the new tyres installed a couple of months after I ordered them. My supplier, and a few others told me that there was a problem with Stinko's supply line, and while they had a 100/90-19 front, there were no stocks of 130/90-17 rears. Anyway, I whipped the wheels off and installed a spare CB750 front wheel on the front just to stop the bike falling off the centre stand.

I wanted to install the headlight assembly but while my NOS headlight shell and NOS headlight ears had finally arrived, the weird "Square hole" mounting rubbers hadn't, and when I checked my Ebay purchases tracking history this weekend I discovered that they hadn't even left the US, a month after I bought them. Great. Today I made some temporary rubbers that will do the job until the new ones arrive, and I installed the shell.

Being colour blind is a b1tch, distinguishing between brown and orange, orange and yellow, grey and light green etc is difficult, and it doesn't help that Suzuki use black wires with a white trace for earth wires, as opposed to Honda using them for ignition wires, black for left indicators and light green for right indicators, all arse-backwards to what I'm used to. No biggie, I managed to get the headlight on/off switch, hi/lo beam switch, horn switch working, and extended the front blinker wires as the wires on the front after-market ones was too short, and the connectors were too small, so I snipped the ones off the old front blinkers, joined them using those beaut heat-shrink-solder connectors and called it good.
The headlight itself was the one that came with the bike. The rim had some surface rust and the chrome plating on the reflector is starting to come off, but the 47(?) year old globe is still working fine, which is good, because I'm not sure where I can buy another? I had to re-tap the threads in the rim as the old ones were rusty, but was able to screw in the shiny OEM screws and all up, it looked quite nice.

I'd disassembled the petcock as far as I was game, but I got to inspect the diaphragm and test it by sucking on the vacuum line fitting (the things we restorers do...) and the rubber seal looks like it's OK. I didn't have as much luck with the locking cap though, I completely disassembled the mechanism and while I think I've worked it out I'm still unable to make it lock in the closed position, so I'll need to pull it apart (for the 10th time) tomorrow and see if I can make sense of it. If not, I'm buying another one. I'd promised the wife a feed of Spagooli, so I packed up. More tomorrow.
