I have zx9r b1 carbs on a 2ltr zetec and need to know what main jets to use.
Ive checked the Kawasaki manual and they are 200 as standard.

From the manual the later c & e model carbs jets are 155 & 160

I under stand the later carbs should be ran on 165 - 170 jets

do i get some 220 jets?

 

Talk to Bogg Brothers or Chester Sports Cars

 

I run them carbs on my 2l with ported/polished head and cams etc and there fine mate, i still have the 200 jets and have no running problems what so ever
