You can either take it back to the dealer or add a PCV, I added more fuel off 0% throttle and it fixed it.

After my starter kickback cal update. My sled usually takes at least two crank tries to start.
This weekend I went to start my sled in my headed shop and it took three crank tries to start. A disappointing pain in the ....

First of all Define Hot Start Issue.
I have not heard this complaint since the 15 update. Be specific. Could just be a bad battery or dirty connections,fouled plugs etc. Need info like is it turning over quickly? Is it idling properly and at what rpm when it is running. How often does it do this?

Put an optimate 4 battery charger on that new battery for a few days if you can, but at least 24 hours and see if you see a difference. Just because it's new does not make it fully charged. 24 hours with a good battery charger is the minimum I would charge a new battery, and charging a few time through the riding season and off season will triple the life of your battery.

You still have not answered what it does when hot. Does it take two or 3 tries to start? Does it never start? Does it crank real slow? Had Friends little kid over other day and he sat on my sled and wanted me to start it. So I did. It started so fast it scared him into crying and he ran away! To him it has a starting problem.

Thanks Testmaster. Actually a video of it doing it is best. 2014 I really am not picking on you just need more info. Back in 13-14 when there were all kinds of issues with hot start majority had to just slightly touch throttle to get them to start. Once 15 flash came out the hot start problem went away. Exhaust has no effect on starting.
