Removed the pan to get at the pump. Had used gasgacinch, must have put it on both sides as the gasket separated leaving some on each surface. A little solvent and it released easily.
In my memory, it was HondaMan who first introduced the subject of priming the oil pump to me. Something I had never done before. But with one exception I'd never dried out a lower end before. And the pump I am using is an eBay piece, virtually new, that was completely dry when I got it. Actually, I think one can usually get away without priming it, maybe prime it with the kickstarter. But now that I know the idea, how can I not? I did a YouTube search and didn't come up with anything for the CB750, but lots of other vehicles, guys prime thepumps.
So we pulled the pump and put it in a Tupperware.
Poured in some oil and turned the gear.
Wasn't really getting the results I anticipated, so we turned it over and poured the oil direct into the pickup.
That got it. Turned it back over and turned the gear, bubbles came out. Reinstalled.
A secondary purpose for pulling the pan was that i had installed it with the original bolts, that I had wire brushed. So they proceeded to rust. Sure its on the bottom, but i expect people to look everywhere, and that would have been hard to explain.
Especially since Spillane's Stainless Kits that i bought so long ago, came with fresh SS bolts for the pan. All pretty now.
The front left gusset plate is doing double duty as the ignition switch mount. When Saldana made it they did me a favor and reinforced the hole with a washer.
The extra thickness caused the nut on the switch to stand proud, even when i got a thinner washer from ACE. So I took the Dremel to the washer and the switch and got it to be flush.
Purchases this week were limited to a spark advancer from eBay. The seller said it was from a 78F. It has a "300" identifier, but I haven't checked to see if that's a 78F or not. It surely would be what i want anyway. Comparing it to other spare advancers (NLA BTW) it is beefier and bigger in many respects. Hmmm.
The weights are bigger and arranged differently from the earlier "300"s I have. Seems to be low mileage, excellent shape. Not bad for $20 considering they are NLA.
What I had noticed is the advancer in the bike now will turn when the peg is engaged in the crank, ever so slightly. Can't know if its the peg or the hole that's worn, maybe both. Of course once the big slotted nut is tightened it doesn't turn at all. But I'd like to know it was indexed properly. maybe the new(er) one will fit tighter.
We need to get the gas tank ready. I'm switching from a right side petcock (ridiculous) to a left side. But in doing so one never knows what interference i may encounter. I had bought the SS bolts and nuts for the gas cap from Mark (HondaMan) years ago, took about an hour to find them. They were in the last place i looked. We'll need to install the new petcock and finish refurbishing the gas cap and install. Fingers crossed the tank doesn't interfere with anything. In particular I'm worried about the carbs, the choke, and the APE frame kit. I'll put a minimum of gas in it to start it. Once we know the verdict, off it comes and goes to the yet unchosen painter. We can continue to run it for tuning withthe umbilical tank.
