If it's a carb'ed bike, has it been stood for a while? Symptoms as described suggest blocked or partially blocked pilot jets and passageways. You might get lucky and clear this with fuel cleaner additive such as Seafoam.
Other possibles include weak sparks, either due to a dirty ignition switch (flush with WD-40) or poor contact between plug wires and caps. Fix this by unscrewing the plug caps, trimming 1/2" off the wire and refitting.
