Is it possible to do a compression test ?
You will need to remove both spark plugs out, crank bike at full throttle for 5-10 secs max, then report back with some figures you got.
If we can start there first, it makes it very easier to diagnose fueling issues if we get the engine out of the way first (since it is the engine that needs to compress well to lift the fuel out in to the carbs)
