I finally carved out some time to work on the brick. I didn't take a lot of pics, but then it really looks pretty much like it did before I took it apart...
One of the changes I made was to swap to a newer version of the fuel injectors. The originals are version 1.1 of the high impedance Bosch injector. I installed version 1.3 injectors. The difference? The 1.1's have a single "pintle" hole that sprays fuel, the 1.3's have a 4 hole nozzle. The newer style vaporizes the fuel better, resulting in better mix and burn.
In the first pic below you see the "new" injector on the left, the original on the right. Then close up shots of the business ends.
The 1.3 injectors I picked are very close in flow rate and impedance to the originals. They are part number 280 150 921, commonly spec'd for V6 Audis in the mid 1990's. The original is part number 280 150 210. I installed new o-rings and gave them a good cleaning before I popped them in.
I while I had the induction and injection apart, I replaced all the fuel lines, the FPR vacuum line, cleaned the AFM, and cleaned and lubed the throttles. I also replaced the perished crankcase vent hose.
I got the bike assembled far enough to fire it up and confirm I didn't miss anything important. I have the lights in the fairing, so next step is to bolt that up and start building the inside.
I've been pondering colors for the tank and tupperware. I am leaning toward silver, something close to the BMW car color Polaris. The angular lines of the bike are very similar to the 80's BMW cars, and Polaris is a great compliment to that styling.
For now, I just want to get it in one piece, make sure everything works, and ride it! :riding:
