wanting to know what i can expect power wise with these mods i got a k&n air filter, yoshimura rs3 slip on exhaust and waiting for my afam -1 +2 sprockets anyone with something close to these mods or any help with what i can expect once i get the sprockets on the bike

 

i don't have those mods... or an F4i for that matter BUT from what i've read on this forum...

k&n air filter... doesn't do all that much
slip on... provides some (not much) gains (sounds great though )
sprockets... increases torque/low end grunt (lose top end)

oh.. and welcome to the forum!

 

you'll love the sprockets.....they are definitely the best bang for your buck. Other mods you wont feel that much, however, the sprockets (-1, +2) you'll notice a BIG difference. Good choice!

 

ya that's what the bike shop told me about the sprockets when they come in and i get them put on i will post another reply and let you know how they are working
