I have the same exact bike and I had the same exact problem. So let me fill you in on what to do. What everyone said is true and good info. But keep in mind every bike is just a little different. Here is what got mine to start in one or two kicks when cold.
First go buy a new plug, then gap it at .033 or as close to that as possible. Your have two problems when starting, one is the dealers fault, the plug gap was wrong. It was like that on mine also. The second problem is what you do when you try and start it. Make sure you are running 91 or higher octane gas.
Now starting the bike. Contrary to what some may say, it is not how hard you kick the bike. With a 4 stroke you just need to make sure you kick the entire stroke and NOT real fast or hard.
Now hold in the compession lever and kick the bike slow about 4 or 5 times. Now let off the lever and find top dead center. You will feel it catch, you will know when it's there by feel. Now this is the most important part. Hold the throttle open 1/4 a turn, then kick the bike one full stroke. If it doesn't start on the first kick, give it another kick or two.
My bike starts in one or two kicks now. I hope this helps you. Good luck and let me know if this worked for you.
