Update:
Looked to clean the air filter and come to find out there is no filter on the bike anymore! The previous owner must have removed it because I have never had one. Carbs look clean, floats are intact, the gas line from the tank to the carbs are not plugged, fuses are in good shape.
All that really seems to be left is to pull parts and go get them tested, or taking the whole thing to a bike shop and letting them diagnose the problem. I think I'll pull the starter and see if it is bad. May also see if I can get it rebuilt for less than what a new unit would cost. If I have to put another $500 into this bike, I would almost look for another old used (working) bike and buy it.
Next update may once again be a while.
