Every single Pingel Ive ever used does exactly the symptom you describe in the On position.. I have to turn it to reserve to not starve the motor at high rpm.
Ive seen this exact same thing a dozen times on different bikes with big motors.. yours is pretty much stock so it shouldnt do that. But on strokers with high compression and above 5500 rpm it chokes them.
I started running Golan petcocks because of this issue.

"Trousers getting sucked into air cleaner" Classic!
You know what, the tank vent under the dash console is taped over with masking tape from who knows when it was repainted, probably 20 years ago. When the damn weather cooperates I'll tear that off and run it again. Imma check the float level for sure, just haven't got around to it yet. It has those damn V&H Short Shots on it which are basically drag pipes. Seems to have newer fatter red wires on it, and I put new plugs in it.

verify static timing so you know you're starting at a correct spot
check for intake seal leaks
check that butterfly is opening all the way
check AC pump shot is strong and pointing down the throat of the carb
check bowl level
check for clogged fuel filter or petcock screen
It varies with altitude, pipes etc but 72 main and 29.5 pilot jets are good starting points and shouldn't create running issues. Might not produce the most power but should perform without creating issues. Your problems, I suspect, fall somewhere else.

I adjusted the float level just now, it was over 1/4" with my thumb pressing down on the needle compressing it's spring. I bent it up to about 1/8". I also gave it an advance curve of 2 on the ignition box and changed it to multi-spark as recommended per the manual. Oh and I also pulled the negative cable off the frame and shined it up. I verified the throttle blade opens all the way and the accelerator pump shoots a good shot Now if it wasn't 30 degrees and windy AF I would go test it. Thanks all!

I'm finding it difficult to understand the way you adjusted the float level. I've been running S&S carburetors for 25 plus years and the best way to set the float level is to adjust the Tang so when you turn the float Bowl upside down the top of the float level is perfectly parallel with the float Bowl housing when you pull down on the float gently till the spring in the needle is compressed.. It is the best way I have found to adjust them..

S&S does recommend Measurements...for some reason..The "upside down" method holds over from the old Round Slide Mikuni...and....Works at least as well!!
