What type idle jets are in the '98 ZX-9? A Keihin type 24 or 25?

not sure about what "type" they are, but my 98 has number 38 pilot jets as standard

I'm almost sure its a type 25. They are listed for CVK carbs, part no. N424-25-38. #38 is stock and I want to go to a 42. I have hard starts and off idle response sucks unless it's on the choke. I might be able to tune on the air screw but this winter it will need the bigger idle jets.

factory pro recommend a #40 idle jet when you cant get it rich enough with the stock #38 with a maximum of 4 turns out on the screws

perhaps take one as a sample to where ever your going to buy them from? or go anywhere that sells factory pro or ivans jetkits and im sure they will be able to tell you exactly which jet you need
