03 z440 vs 04 450r

[Punk'd]

My friends getting a 440 kit put in his 03 z400. So we both are curious on what the outcome would be?

z400: Also will have a white bros pipe with the 440 kit, airbox lid OFF, rejetted and a uni filter.

450r: curtis sparks pipe.. with airbox lid OFF. Rejetted to 190main 50 pilot.

Thanks in advance.

I'd say the 450R will win but that's just my opinion.

I would say 450R too, keep us posted!

well my best ridding buddy has a z440 12.5:1 compression, hot cams, valve springs, fcr carb, k&n air filter, CT pipe, and runs on 109 octane.

when my bike had sparks pipe and air filter we ran neck and neck BUT if we went from a dead start i would pull a quad lenght right away and just hold that gap the rest of the way.

now that ive got a piston and cam i blow it out of the water

I think it will be a intresting race
