I did'nt notice the need for jetting changes when i did mine, but i would think it would be slightly leaner if any thing.

I wonder if it has to do with the K&N filter? I think my jettings a touch off since I've put mine in.

I put a twin air back on mine, i honestly think the KN lets fine particles by. I did a top end and found some scars, plus some fine dirt on the grease in the air boot......

I would never trust those K&N filters...

The whole concept doesn't make sense to me in a dirt environment.

Seriously, it is getting warmer right now and the bike will run a little fat in hot weather.

is there a lot of power to gain by removing the screen?

Just curious why you remove your backfire screen if there are no power gains?

had a KN airfilter on there. And with the filter and screen gone, it did seem snappier, were not talking night and day, but you could notice...

A K & N -DOES- flow more air...but...it ain't as good as a foam filter for keepin' the crap outta your motor! (It -WILL- pass more dirt than a foam filter...NOT GOOD!

Don't even get into what happens when a K&N get's wet.
