Prior to unplugging the vacuum port - I cleaned up the wiring to a very simple setup - bought one of those starter switches that you bolt straight on the starter. This allows you to engage the starter solenoid directly without relying on a relay or start button. Then I got some new battery cables - 2 awg and ran them straight from battery to starter hot and starter/primary ground. Then add another wire straight from battery through one of those Harley chrome on/off and run switches straight the to coil and ignition pickup. Literally 3 wires for the start circuit. I think there was something in the older hacked up wiring that was probably drawing voltage. I had done some voltage drop tests across starter and then battery and they were quite off - battery was going to like 9.6v but on the starter it was like 5v. So cleaning up the starter circuit helped a little. Even if that wasn’t the cause directly now I can be damn sure that there is no issue on the electrical side
Once it got running with the voes vacuum port plugged it does seem like an issue with too much fuel. Will have to play with the carb a little. I was able to at least run the bike for a few minutes and get it warmed up which was a great relief. Now I can focus on fuel delivery and not have to worry about issues with the motor at least. Thanks all - not home free yet but def some type of success at least..

I am by no means an expert on CV carbs to say the least. I have never ran one. No experience. From what I have read and understand is that if you are running a stock CV carb is that the vacuum hose from the intake manifold to the VOES must be connected for the engine to run correctly. Wild guess. Maybe a bad VOES? My 1995 had a S&S carb on it when I bought it and VOES was disabled. Crane HI4 ignition. But. That is irrelevant to your situation. Good luck.
