1986 v65 Mag - will start with full choke only but will die as soon as you back the choke off or crack the throttle. Has fuel pressure and is warmed up. Last year it did the same thing but once it warmed...
You need to disassemble and properly clean the slow circuit/slow jets of your carburetors. Unfortunately, Your carb rack is very delicate. There are some brittle and expensive($40 each) crossover pipes that may crack or leak if the rack is removed for cleaning. I would try lowering my fuel level to just the lower tank and adding half of a cup of "Chevron Techron" to the gas (basically you want one gallon of gas with a shock treatment). Unplug the fuel line from the fuel pump and pour some Techron directly into the carbs. Now start the bike and run it long enough to make sure the treated fuel is in all the carbs. Turn off the bike and let it sit overnight. In the morning drain the carbs, restart the bike , and idle or slow drive till the carbs idle again( usually 5 to 15 minutes). If bike is starting to idle, drive to the gas station , fill the tank and drive the treatment through. With any luck this will solve your problem without an expensive disassembly/cleaning. Use "Chevron Techron", not Chevron fuel treatment with Techron, Techron is more concentrated.
