Acceleration between 3k - 3.5k RPMs

I have an 07 with 8300 miles and a 2bros slipon. In first or second gear without opening the throttle anymore than it already is, the bike accelerates quickly between 3K - 3.5K RPMs. It's not a problem, just wondering if anybody else noticed this, or if it's just my bike.

My guess is that the air/fuel mixture is ideal in that RPM range, and "off" above 3500, and that's why you notice the change when the bike reaches 3500 RPMs. I bet a Power Commander and a custom map would smooth that out for you.

I have a 2Bros slipon and about 12000KM on my bike, it's a 2011. Haven't come across this problem. Maybe cleaning/replacing your air filter might smoothen this out. You certainly don't need a Power Commander with just a slip on.

Is your air filter stock or aftermarket?

EDIT: Needs moving to the troubleshooting section.
