I'm sure this has come up before but, I have a 2002 gsxr 1000 and a couple years ago i had a k&n air filter,but my bike ran like crap when i added it. I haven't rode much in the last two years but my brother just got a bike so i'm getting back into it. My quetion is I was think about buying A bmc AIr FILTER , do you think i'll have the same problem Right now i have stock. I want to add i have a devil SLIP ON pipe. I also know bmc make standard and race models( 10 $ difference) your thoughts on that too?
oR SHOULD I JUST GET A Power Commander?... i dont want to wste money .my bike has over 20k on it.. thanks guys
