Drain off the old fuel from the carbs , carb drain screw is on the botton of the float bowl. fill with good fuel and try again.
If no check for spark remove plug fit to coil rest against the head and turn over. Does it spark?

SOURCE: fuel starvation
There are three things all at the same time the bike needs to run:
If you use starting fluid into the intake, and it continues the same, then fuel is not the problem
Use a compression tester to see if the pistons come to spec
Check the spark plugs, maybe try changing them with hotter plugs or just new ones. Also check the coils and stator for proper ohms.
You might see a little compression loss by a cam being out of timing, so you might check to see that your cams are timed right.

Hi, Sitting not good ! That is why the petcock has an off position. Spray some starter fluid or some fuel in the carb intakes and see if cranks, If it does, the carbs have to be disassembled and cleaned. Good Luck to you!

I would sujest makeing sure that the bowl on carb is full of gas, if that is fine then i would try the times outidle screw, all way snug then turn if 1 1/2, hopefully checked plug first off may be needed to be changed. hope this helps

Start the bike till running temp is reached .while the engine is hot ,change the oil and filter.take great care not to burn yourself .When the engine is hot you will find the oil drains away much faster and all the old stale oil will drain out of the engine & gearbox & clutch ..Once you have replaced the old oil with new oil and filter .this should cure the problem of stiff gears .
