jeffery ;

adjust your float height sound like to much gas going in to cylinder flooding it out,next time you park it turn gas off  then the next time you go to ride turn bk on to see hoe fst it starts and how long it runs o,k if you need more help i got you covered ok,and if this doesnt wrk re-jet the carbs ok

Answer
i had same problems with a bike in my shop go to the drain hose on the carbs blow into them while the bike is running if the bike idles up ,take a smll wire run it through both drain hoses so it can breath youll be fine.
