So i got my carbs cleaned and synch'd.. before the bike was at the shop it started up pretty smooth.. now it needs some throttle to start... The spark plugs are no more than 2 years old.. this just started after i got my bike back from the shop.. its not that big of a deal but if i choke the air and just hit the ignition, it will not fire.. Before the carbs were cleaned, i would do the same and it would fire.. any suggestions

 

and it does this when its cool and after i ride and its still warm
