zx9r b1 carb question

[Guest]

hi all im new to this site so hi to everyone .i have an issue with my zx9r b1 as a lot of people do i think. anyway the issue is ive stripped the carbs and 2 of the air leek jets that go with the main jets are different to the other 2 and when i say different i mean on 2 of the jets there are 3 holes and on the other 2 there are 2 holes .what i need to know is do these air leek jets match up with the slide needles in any way because they are marked so as you put n67t needles with cylinders 1 and 4 and n67u with cylinders 2 and 3 .any help would be good if there is another b1 lover out there .

i would of said it is due to 2&3 running slightly hotter due to being the inner cylinders and hence having slight amount of extra air to stop them running richer the hotter they get,but i might be wrong as i often am

Sounds logical Captain.....it's either that or the Klingon's are off the starboard bow......

thanks it does sound logic .i have put the leak jets with 3 holes in working with pots 1 and 4 and the 2 holed jets with 2 an 3 would you say this is correct or would you swap them around

more air into 2 and 3 so 3 holes in carbs 2 and 3 in my mind

i will try this and see how i get on as ive strippped them that manny times i should be able to do it with eyes shut.also i have mixture screws turned out 1 and 3/4 i was wondering would it be a problem to turn them out 2 turns.

I think you need to run the bike and then check the plug colour to see if the mixture is correct.....then go from there....
