Just like title says, will it? I found performance cams for the f4 and the 03rr but not for F4i, and I've been reading around a and I know the rr Cam won't fit but i'm looking to get a little more power and I thought this might help... Thoughts? Ideas?

 

not sure it would increase power unless the lobes are bigger, and if thats the case it would be interesting for a fuel injected bike.
do you allready have a power commander + air filter + slip on, or fuel exhaust?
im taking a guess here thinking that the fuel injection is going to only put in x amount of fuel per RPM and if the lobe holds the valves open longer it doesnt matter

 

The only difference is that the F4i has 0.04mm more lift on both cams. The standard spec is within a range of 0.16mm so good F4 cams would likely have more lift than even slightly worn F4i cams.
Cali F4i cams have 2mm less lift on the intake and 1.5mm less on the exhaust cam.

Just in case you're looking at swapping the cams be aware that the F4i exhaust cam has the cam position rotor on the end of it as well.

 

I do not have power commander yet, but that is what I'm getting next, the reason why I asked about the cams is because I found a set of aftermarket cams for the f 4, the are 270/260 cams
