Hey fellas! Its been almost 6 months since I've been on here, I've been an intern for Mercedes Benz and am in Stuttgart Germany, and yes, I miss the hell out of my 01 6r. Anyway, my question is this. I have a scorpion slip on and a factory stage 1 jet kit on my bike, I want to get a K and N filter for it when I get back the firts week of December. Since the filter will flow more air than the stock filter, will it mess up my air/fuel ratio now that I've already done the jet kit without the filter. Will the bike run too Lean?, or will it be ok if I add the filter to it, and also, has have you guys noticed any differences with your K &N filters over stock? Thanks guys. Continue to ride the hell out of your 6r's for me back home.
