Hard acceleration smoking

I have a 2013 renegade 1000. I noticed that when I hammer the gas it lets out a small amount of smoke. I would say light grey looking. It only smokes when I hammer the throttle. It does not smoke any other time. Runs like a champ all day.

My question is where should I start with the checks? I purchased this bike knowing it to be a project.I am just new to the can-am world.

I don’t have a problem rebuilding if need be, but I just need some direction on if I need to do a complete rebuild or a top end kit.

Thanks
