Was that the first year of Fuel Injection for the R1? My 2004 FZ1 had the last carbureter version of the R1 engine. Yamaha added a set of mid range cams and a tuned exhaust flap to boost low and midrange power. For a 1000cc bike, that thing popped a wheelie like it made money doing it.I had a blue/white 01. I think my 3rd or 4th bike. GD that bike was fun. You'd twist the throttle and it felt like Jesus was sending you to Mars on a rocket LOL
What scared the shit out of me was that it pulled HARD once you got over 8k... **** me running that was a lot of fun...
