I had a honda V4 that had similar problems. Even after riding it was a crap shoot whether it would restart. A local bike mechanic told me that the ignition drew power through the same circuit that the starter did so when the starter was working harder the spark got weaker. He suggested rebuilding the starter so it wouldn't draw so much juice. It worked. No more hard starts. Look into it.
