Going big bore generally adds more torque throughout the whole range. I noticed it pulling harder from off idle all the way up through to 10,500 rpm. This bike's rev limiter is at 14k rpms...I never went past 10.5 though so I'm not sure if it signs off at the very top.

I've had this bike for 4&1/2 years now...was thinking about buying a new $12k 450. This bore kit and exhaust made it a different bike...bought the ole' girl some time! And it only cost me about $900! (wife's happy about that). I will still be shy about 10-15 horsepower to the 450s and 350s on my starting gate...but the fun factor just went way up!
