Nice! I may have missed it, but what handlebars did you use?

So, took it for a maiden in its new form, and i absolutely love it. One problem... it left me stranded 45 mins into the ride. I got a jump from a local, and was able to get home by keeping the revvs up above 6k the whole way.

Got it into the garage and did a quick recon. Battery at 10v, r/r showing good resistance on all 3 poles, then started it and checked each leg of the stator.  1 was at 50a, one at 55a, and one at 0. Checked with a beeper and its not grounded... just open.

So I checked the donor bikes stator (luckilly it was off and I could bench test), and all 3 legs are good... no ground outs, and all show 0.9-1.0 ohms resistance between all legs + and -.

Looks like Im moving forward with a stator swap.

Found out the problem wasnt really a problem... it was a parts issue. I left the stator for the kick-start engine in when i installed the starter from the other bike. Turns out they are different part numbers... and the kick-start stator isn't 3 phase.

Swapped the stator in about 20 minutes. Fired it up with 11.6v on the battery and it quickly jumped to 13.7v with a steady throttle at 3k rpm. The old stator would barely keep above 12v when running.

Test ride tomorrow!

Woohoo! Got the new stator in and its charging perfectly!

After the bike warmed up (this has been a constant problem) the idle went wonky. I tore into the carbs again... balanced them, did everything in the book... until I found the answer.

I installed the butterflies backwards and they werent sealing. Didnt even notice they were tapered on the edges. Flipped them around... re-timed, did the valves, checked the points, gapped the plugs, balanced the carbs again... and we have a runner! Let it idle for a good 10 minutes... kept blipping every minute or so..  rock-steady idle! Even with my pods and custom pipes, shes a runner! Now to put some miles down!

All the extra tinkering led me to build an actual bike bench... shop is coming together.
