Re Jet after MGP Growler?

Hi, I put a MGP Growler Slip on to my '12 ninja 250. Do I need to re jet it?

Mmmmm not sure how does it ride? Is it choppy? Does it lag in any rpm range? It's really up to you and how the bike feels. If you get it dynoed you can get a better feel for it.

I don't think you need to re-jet with slip-on, you might be able to adjust a screw on the carb to tune the air/fuel delivery, that's if your bike is running a bit lean. I have a full exhaust on my bike, I'm not sure if it's re-jetted but it runs pretty smooth. I haven't check the spark plugs yet though. Every bike is different, some will run rough after a slip on and some will run just fine. The fuel gauge on these ninjas are never accurate as well.

This is a link that might shed some info:
