I own a 98 900rr that has been customized quite a bit (custom paint. extended swing arm, lowered suspension, a lot of chrome, Hindle full exhauust,and stage three jetting). I've had the bike for 10 years and to be honest theres nothing out there saying BUY ME - BUY ME. I love the look and feel of my rr, but I can't help but feel that it's time to do some more upgrades (I owe it to the bike). I thought about a turbo, but the price is scaring me away since I'm considering a fat tire kit (240 or 300). That leaves nos, so my question is, is there a shot that I can get that won't cause me to have to do engine repairs down the road, but will give me a noticeable difference in performance?
