2004 F4i performance upgrades
Hey everyone,
I've been doing some reading on performance upgrades for my bike, I would like to get alittle more jam out of the bottom end. What I've gathered is I need to change my gearing, I need to replace my chain so I figured now is the time to do it. Most recommended is a -1 front and +2 rear, my question is how badly does it effect speed at top end? I'm not too excited to loose top end in the first place but I know its the trade off for gaining on the bottom end.
Also, is the power commander really worth it? And is there anything additional I need to know if I add the power commander after changing the gearing? Bike has a slip on and K&N filter so no problems with air.

Any recommendations for an air filter? Or would a stock one work fine

Stock flow pretty good. There are some other washable ones out there that flow better, but I can't remember which ones. I think bikemaster has a regular and race version... but don't quote me on that. If you look around the forum, you will find info on k&n being restrictive.
