I had/have a similar issue as you. See my thread as it might help you troubleshoot. I ended up getting a new rotor from Jim, moving my needle jet to the leanest position and built a new rec/reg for reliability sake. I also went one size up on the air jet. Bike seems to run nice now before...
Thanks Jim I have corrected this. The metal part of the brush is now sitting flush in the saddle of the brush holder. The terminal has been corrected to sit on top of the brush tab.
You know, I have no problem making mistakes (I have made A LOT in this thread alone) as it affords me the best...
I don't know what I am saying except what I already said. I don't understand it either, so I am assuming I am doing something incorrect in testing. I keep reading and reading and troubleshooting to no avail.
If I am not damaging anything by riding I will continue to tinker away and ride my...
1. 13.22
2. 12.84
3. 12.75 at 1200 rpm
4. 13.5 at 3000 rpm
She slapped just fine :)
Grounded green wire to engine at the brush at idle and read 0.9v
Also getting 10.99 volts across the brushes with the ignition on (not running).
I did as mentioned and shorted the green wire at the brush to the battery ground and witnessed no jumping in voltage. I only saw about 0.5 V on my voltmeter while revving. Is that correct? Or did I not follow your directions correctly?
I checked the voltage at the battery after doing all this...
It is this regulator:

OG part number 4475112 which cross references with VR794 from what I can tell in this ebay listing...
Reading further in my Haynes manual again, it does sound like the regulator could be the culprit here if I am not achieving 14.2 to 14.8 volts at 2000 rpm. I know my connections are tight because I have cleaned the connectors and applied dielectric grease. I have also checked for frayed wires...
I bought the Fiat regulator and windynation rectifier. Link for what I am following below:

So if I tested my reg/rectifier (page 1) and it is showing OK, what's next? Is it worth building out this...
OK I just did it again with the help of my girlfriend and at 2500 rpm I was reading around 13.4v as mentioned and climbs up to 13.5 -13.6v at 3500 rpm.
It seems the volts climb as she was revving the bike. I thought I caught the highest of about 13.6v around 3500 rpm. Did not rev higher than...
