On ebay Budd, anything you need for that bike is on ebay.

just start the bike up and shut the petcock off and let it run till it dies carbs will be clean no gas

Look for intake leaks spray carb cleaner around the intake boots being careful not to get any near the mouth of the carbs. If there is a leak the rpms will change. Check the pipes careful not to get burnt but check for the same temperature on both pipes. If one is a lot hotter. You have a problem with the colder cylinder(compression, spark or air fuel mixture) If it has all 3 of those in the correct specification it will run. If all that checks out then sync the carbs. 2nd response: The timing gets a signal from the pickup coil. That could be bad. If it is single coil it will affect both cylinders. Both fire at the same time. One plug is a wasted spark because it is on the exhaust stroke. Dual pick up coils would fire each cylinder independent of the other. You could also check the fuel lines and make sure there is no obstruction or drawing in air. Check the float height to see that your bowls aren't running out of fuel. I should have mentioned this first but make sure your plugs and wires are in god shape. If it is hard to start and gets worse the warmer the engine gets check the valve lash. Hope that helps. I am out of ideas on what it could be if not any of those.

I would bridge the starter relay to see if it cranks (use pair of pliers to touch battery side to motor side, expect few sparks). If it cranks that rules out battery issue and terminals to battery. If you pass that test ok then move onto next solution. (next solution) Im thinking you should take a look at the "block connector" coming from the switch gear with the starter button on. Could be corrosion built up in this connector preventing continuity. Also check for corrosion or crud built up within the switch gear itself. Pay attention to back of the starter button connection points.
