I did. I re-wired it to the coil power wire. I tested it and it gives hi 11v output. just about 12v. I made a tap wire similar to the one provided with that R/R upgrade where it taps into the rear brake. it works! I dipped, flossed and cleaned the carbs with guitar string, cleaner dip. Added bigger mains this weekend. Trying out 132.5 mains where the 127.5's were'nt giving me enough on the top end.
Installed the carbs, tightened the valve cover bolts a little again, made a thin aluminum plate that blocks any access oil from the wiring and electrical system, added a small filter to the valve cover blow off tube, and test drove it.
The bike screams crazier than ever on full throttle, idle-3/4 throttle sucks ass. The needle setting is on the 3rd clip down from the top. Air screw 2 1/2 turns, fuel screw 1 turn out.
Ill set the needle clips to the very bottom setting (lifting the needle the most is can before shimming), and the air screw to 2 turns and fuel to 3/4 and see what happens.

UPDATE: Over the weekend I got 132.5 mains and installed them after cleaning, dipping and flossing the carbs with guitar string. First test ride: idle-3/4 throttle sucked ass, WOT screamed like a bat out of hell. I pulled the carbs, moved the needle clip to the bottom position, lowest I can go which would esentially raise the needle as high as it can go before shimming, and went on my second test drive.
Second test: I timed the ignition with a timing light and my static timing was right on! Holy cow I finally dialed this thing in. For some reason I still leak some oil from the valve cover so thats my next step but the bike screams from idle to wide open throttle!

Video coming tonight
