330 Big bore kit

I was just wanting a little bit of info. Does the 330 kit make that much difference? Thanks

about 25% increase according to the guy i spoke with at motojoe.com yesterday!
that was there 92 octane pump gas 330 kit.
price was 345, im highly thinking about this route instead of selling my 300 for a 400ex.
