Diff between ZX6R and ZX9R Carbs?
deezee - 5/7/09 at 06:15 PM

Been searching here and google to try and find the differences in ZX6R and ZX9R carbs? So far all I can see is that the ZX9R has diff jets?

Surely people aren't changing nearly twice as much for ZX9R Carbs when its just a trivial difference? I'm after a set of carbs for my 2Ltr 150bhp RS2000 16v Engine.

I think the choke sizes are different.

Suggests that 6's are 37mm and 9's are 40mm.

can confirm above, would think both would still require rejetting.

The choke sizes are different as above ZX6Rs measure 37.5mm.

ZX6Rs have adjustable needles, not all ZX9Rs do, which makes getting mixture right a lot easier.

Jets will need increasing on both. Mine are currently 1.6mm [ZX6R on a 2.0 Zetec].

Alright, cheers for the advice. I'll just grab the cheapest ZX6R or ZX9R Carbs that turn up.
