Bike Carb Jet Sizes?

[Guest whiz]

Guys looking for some figures for jets sizes for a friend who is running a 1.8 zetec with ZX6 carbs. its not running great due to the carbs not being set right does anyone have any starting sizes for the idle and main jets. to get the car running better.

What size are the jets currently?

My zx9r jets are 155 and plenty good for a 1.8 zetec.... Jet size is way down the list of importance...

Air corrector jets and air/fuel mixture screws are more important as is float level, and making sure the diaphram is well sealed so the needle lifts cleanly and fully....

 

I found the air corrector jets needed blocking completely, mixture screws 2.5 turns out from fully closed, floats were ok and didnt need moved.

have the carbs been balanced agree with keith jet size dosent really affect running I found 1.5mm good on zx6 carbs as a starting point

He can get a hold of a wideband. Think that is best I don't think it's full throttle he is lean at
