I've been working the rear brakes through the weekend, just pumping the pedal whenever I walk by, and when I had to move the bike today it felt like the brakes are working properly now. As you said, probably something in the system clogging it, but it feels good now, Haven't had a chance to bleed the fronts again but I did get a couple new bottles of fluid.
Well the engine is about 99.999% done. I have 3 quarts of oil in and not seeing any drips. I'll top it off once I can crank it over and work some oil into the passages. The carbs are back in place, but there are three unused vacuum lines on top -- were these supposed to just be capped? The coils are hooked up, the throttle is adjusted towards almost fully closed until I can start it. I dunno, I think once I can put some gas in the tank I'm ready to test it... except...
So I hooked up the battery today. Looking good so far, the brake light works, blinkers work (need a new blinker module for the hazards through). The problem is I can't seem to get the starter to work. Since I don't have the key, I took the switch assembly off the bottom of the key unit. It has indents you can feel for each position, so the lights come up when I turn it to run, but going fully to the starting position, the brake light comes on bright but the starter does nothing. I tried checking for power at the relay, but between ground there is no juice on any of the wires. So I'm pulling out the wiring diagram to see what I can find. Keep in mind NONE of the dials are hooked up (there's quite a bundle of unconnected wires hanging out of the headlight), but I do have all the connectors from the handlerbar switches plugged in under the tank, and I connected everything else to the wiring harness as I found matches. Besides what's in the headlight, the only large plastic connector not plugged in is for the gas tank. I also have a red wire with blue stripe in front of the battery box, and a solid red wire behind the battery box that are unconnected (small gauge). I also re-checked the fuses and they're good. I must be missing something still...
But damn, it really looks like a bike now! Oh yeah, and I finally got the foot pegs on so I can sit on it now. Hmm a little tight for my long legs, but we'll see how it rides.
Oh, I also got the headers on. The mufflers come straight back, but I have an idea that I've like to tip them up so they follow the angle of the board that the foot pegs are on. So do this right it looks like I need to take about 1.5" off the header pipes, then somehow bend and angle into them that will allow the mufflers to still be attached. That may be a Winter project though.
[EDIT] Yeah ok, you can tell it's been awhile since I've ridden. So I'm looking at the schematic and I find the ignition switch, and right next to it is a starter switch. Starter switch??? I go back out and look at the handlebars, wipe the dust off the 'run' switch... oh yeah, push to start! Too bad it wasn't that easy. Turned the ignition switch full clockwise, hit the button, still nothing. The brake light didn't even dim. I reconnected the red plastic connector from that switch a couple times to make sure it had a good connection, but still got nothing.
[LAST EDIT] OK I think I may have figured it out... I plugged in the dials and noticed there's an indicator for neutral... except it's not coming on despite the transmission definitely being in neutral. I'm guessing that has something to do with the green wire I hooked up under the chain cover, but even when I pulled in the clutch the light still didn't come on. Erg that doesn't sound good. Any thoughts as to what I'm missing here? If I pull off that cover, should I be able to ground out that wire and make the neutral light come on? The schematic also shows a 3-position connector going to a starter cutoff switch (two black and one blue/orange wire) but I can't find anything like that along the wiring harness. Now I'm really lost!
