You've increased the air flow.
As the bike's new to you, you should consider doing simple servicing yourself.
This would include the air filter, and i would recommend a K&N air filter, which from your description of performance the bike would really appreciate.
Don't worry about the price, not only is it the last air filter you'll ever buy for the bike, but the grin factor and throttle response is more than worth it. :thumbup

More people are born because of alcohol than will ever die from it.
I used to use k&n air filters a long time ago and had to oil them after cleaning, are these k&n filters the same and if so do they come pre oiled.
Yeah, they'll come ready to go.
After a bit of research i found out that the cleaning spray that you're meant to use has the same ingredients as washing powder, so i clean mine now using this in warm water.
I use the K&N oil spray though once dried out. Normally a job on a hot sunny day. 8)
