I purchased a 99 r6 about 2 weeks ago and am already becoming used to the power. I love the lightness and flickability of the bike, so i would rather mod it instead of going to the liter bikes. What can I do to get a significant increase in power? Are there stroker kits available? Head packages? I'd like to stay away from the nitrous. I weigh 165lbs...should I just get an r1? Someone please shoot me in the right direction. Thanks.
