'86 SE-i That Followed Me Home

While the tank is still electrolysis-izing (patent-pending), I wanted to tackle the throttle cables as accessibility goes in the toilet once the tank is back in. (Same for the rear brake master cylinder, next on the list) The throttle was really slow to return to neutral position, so giving it a good clean and lube would be the first step before replacing cables. With cruise, the SE-i has three cables to play with. I removed them one by one and gave each first of healthy does of brake cleaner shot through my cable lube tool, then some dry lubricant spray. Upon disassembly, my problem child ended up being the cable that runs directly from the throttle to the intake manifold. Gave it some extra squirts and care, now all snaps open and shut like it should.

I spent time this morning detailing the ECU connector (C56), The 13-pin that feeds some of its lines (C51) and the 21-pin right off the relay/fuse box (C1). Wanted to know each color, where it goes and what it connects to. Will help for swapping in a Speeduino or any other changes I decide to make. Not 100% complete as I couldn't find all the colors in the wiring diagrams or manuals and haven't begun tracking them all down yet on the bike.

The aftermarket pump replacement arrived yesterday (Airtex E8312 knockoff), identical to the one I used on my 85 resurrection. I remembered it being way too small for the original mounting bracket and using lots of rubber sheets to make up the difference. This time I designed a sleeve to make up the difference since I had the original pump and its rubber sheath that fit inside the bracket. Took a few test runs to make sure the pump was snug in the sleeve, but eventually came up with a nice solution. As you can tell, pink is still loaded in our 3D printer. I'll be picking up some ABS black soon, maybe on a Prime Day sale.

Other part I worked on today is the rear master cylinder. The piston is firm about its desire to remain inside the bore. After soaking for awhile in penetrant, I was able to tap it down a bit with a hammer and punch, so at least broke it free. However, my attempts to blow it out with compressed air as I've done previously on clutch and front brake MCs has been met with failure. I currently have it soaking with some penetrant sitting on the base of the piston (MC is sitting upside down) hoping it might soak through and give me a chance to blow it out. I haven't been able to 100% plug the second outlet, so going to pick up a bolt for that tomorrow and give it a shot. Otherwise, I'll resort to a grease gun and hope I can find the right zerk fitting.
