Howdy folks. I've got an odd one for y'all, and I hope I can learn something here about this.
I've got Over 500 miles on my bike and engine, and this seems to be a recent Running Problem. These days, the bike will bog out and run like crap with the gas valve all the way open, (running too rich?) and of course she'll stall out and die with the valve all the way closed. (Obviously too lean.) She seems Flooded out when the valve is all the way Open, and of course she's Starving for fuel with the valve fully closed. What gives??? What the heck happened here?
To get the best performance these days, I have to about Constantly play with the fuel valve during a ride. She runs the best (28 + MPH, Consistent!) somewhere between full open and fully shut off. About a 1/4 open seems to be the best place to have the valve set, but this is Not a consistent setting.
Does anyone have some advice about this running problem? This has me Totally Stumped!

I have checked the carb's Float. It's OK, it shuts the fuel off to the bowl when it should. Dad and I have taken that apart a couple of times and all looks OK in that area.
Venting of the gas cap on the tank seems OK too. We blew some Compressed air up the fuel line and she'll relieve the pressure build up. I assume this means that the Vent is working as well.
The gas valve is good. When it's Open, it's Open. When closed, she's shut Off. I have an In Line Filter now, and not the built in Tank Screen/Filter. It used to run just Fine with the valve all the way open with the in line filter, so I don't think that the filter is an issue.
