If the fuel is not going from the tank to the carb then into the engine it won't run. You could have twenty gallons. Humor me and insure you have full fuel flow to your carb and that it is entering the cylinders. When you post that the plugs are soaked and still no response of firing then move on to next fix.
It doesn't take much to open the petcock. When I drain my tank I use a brake vac like the one in the pic. No more than 10-12 in. HG, you don't want to damage the diaphragm.
Hey! I have one of those. Tank is off the bike and drained. I'll try that in a little while.
Not carb cleaner, that only works if you use a tiny bit, any more and you kill ignition. You have compression, with your hot wire you have plenty of spark so it's not the coil at this point, next is fuel. If your plugs are not wet after cranking it enough to burn up the starter clutch then it aint getting enough fuel. If it fires with ether you know you are on the right track...
I'm guessing you have never had to siphon anything before.
To drain your tank you need about 4 feet of fuel line. Put one end in the tank as close to the bottom as you can. Then suck on the other end till the hose has gas in it then just put the end you sucked on into a gas can sitting on the floor.
This method won't get all the gas out of your tank but it will get 90% of it.
I had to do this a couple of time before I changed my petcock to a non-vacuum operating one.

Last time I did THAT, I was tasting fuel for a week......I'll ask my son to do it.......
Actually, she's drained. I'm going to get some ether.
