It's been a while since my last update. As for past problems, I was able to pull out one side of the front wheel bearings, then I slipped a very slim shim on top of the spacer, before pressing the bearing back into the wheel, essentially lengthening the spacer just tiny bit. And voila! It worked like a charm! No more binding wheel bearings and I was successfully able to torque down that front axle to 60 ft/lbs.! Yay! That will surely help the steering system rigidity.
I tried filling the rear brake system, but wasn't successful. I tried to burp it. Also used a MityVac to suction the fluid through. I still never got to the end of the air. I got tired of trying to solve such a simple task. I still have a couple of tricks up my sleeve, but I thought I would give it a rest and move onto something else for a while- something that I've been avoiding since the very beginning. The electrical system.
Mind you, it's been over 10 years, since I dismantled the bike. When I pulled out the electrical harness, I tried to label the ends and take lots of pictures best I could. But over the years, some of the printing on the Dymo tape had faded and become illegible. Plus many moons ago, had some shop in Concord, Grumpy Bear (since defunct), rebuild my alternator. When they returned the bike to me, they used whatever colored wire they had on hand, and they hard-wired the alternator to my harness, doing away with any connectors! They just crimped all the wires together! I was young and naive. The bike worked, so what did I care?
Anyway, so for me to wire the alternator to the harness again, I wanted to do it right, to do it stock again. When Paul built my engine, he installed the original correct colored wires with appropriate connectors, minus one which I didn't happen to have at the time. But in order for me to know how to connect the alternator to the electrical backbone, I had to rebuild the old wiring system, marrying the original parts (wires), just so I could realize what had happened. So my old harness didn't have any alternator connectors, plus some it had other issues. I just happened to have three RD400 harnesses!! 1) my original dilapidated harness 2) one that I had purchased from Australia through the early days (late 1990's) of internet buying/trading and 3) I don't even know where this harness came from- I probably just bought another one off eBay.
Well, after careful analysis, I realized that that Australian harness had too many wires in the front. Let me just put this out there- a simple disclaimer- I suck at ready schematics. So I was afraid to just cap off the "extra" wires, not knowing if I really need them or not. But luckily, the mystery harness was very similar to mine, so I decided to use that one. I did have to re-wrap much of the harness, but it cleaned up quite nicely!
Since I'm using high output coils with more resistance, I needed to get rid of the resistor unit. I did have to look at the schematic to figure that one out, but it wasn't too bad. I had to construct a robust and complicated spreadsheet with all the connection numbers and appendages they belong to, which really aided in patching together the front of the bike.
I spent a few minutes just to hook up the battery to see if I was on the right track. Moment of truth! I turned the key and the oil and neutral light came on! The headlight worked both low and high beam. And the rear turn signals worked, but they didn't blink, because they're LED. So that's a huge step in the right direction! Encouraging.
Tomorrow I'll start attaching the oil tank on the bike. I might be able to fill fluids too. If I'm lucky, I might try kicking the motor over!
