To me it had more of that intake sucking sound at idle and a lil more growl at Wot..

how much for that carb? I am interested, 39mm or 41mm?

[krt400ex]

i think that the 450R carb is a 42 millimeter. the '06 and up is a 40

True but the 06 is an FCR

From what Iv'e heard you'll notice more of a gain when you put it on a 440 compared to the smaller bores..You'll be real happy you bought it...
