Have you made any adjustments to your idle mixture screw? I would start there. Williams1 has a good write up on the proper technique for idle mixture screw adjustment.

Hard to start cold but easy start warm is usually tight valves

Hard to start hot but easy start cold is usually jetting or idle mixture.

Are you using the hot start lever, hand off the throttle?

ya i keep the hot start pulled and dont give it throttle it just started to happen to my bike yesterday and before it ran perfectly. the only thing i have changed is the oil and the air filter.
