Look at the comments, you’ll see my name in the comments. I have a 1982 KZ750N with CV34 carbs on them with a #125 main and a #62 secondary. What do I need to do to the jets to run pretty much open exhaust and 4into1 performance air filters? Here is a photo of a comment I sent a guy. He has a very similar setup to mine and I was curious what he ran with the jets. He said this.....

Hi John. You should use a Dynojet kit for that.
#35 #62 #125 is stock jetting with N01A needle.
#35 #62 #DJ130 and DNO103 needle (clip in 4th groove). This needle has a base diameter of 2.49mm VS 2.50mm stock (thus making idle to 1/8" throttle richer). This setup is for 4 into 1 exhaust and K&N replacement filter inside airbox.
#35 #62 #DJ136 and DNO103 needle (clip in 4th groove). This setup is for 4 into 1 exhaust and individual K&N air filter pods.

Look at the comments, you’ll see my name and what he said.

Fuel mixture screw. 3.5 turns out... you can´t go further.

So what do you think he was referring to?

He used the fuel mixture screw 4 turns out. It is beyond limit... that tells you need a bigger slow pilot jet OR a smaller base diameter needle.

Where do I find a larger slow pilot jet?

So just to get this clear, my 1982 KZ750 Spectre with CV34 carbs, pods from 4into1, and straight though exhaust. I will need to maybe take that air fuel mixture screw out 1 or 1/2 turn. And get bigger slow pilot jets?

Does that sound like a plan?

So will it be correct if I get a # 35 or #40 pilot jet from jetsrus?

First check what your carbs already have.
Spectre model have only 2 jets (slow pilot jet and primary main jet) and a fatter needle N10A.

Okay, well I currently have a 125 main and a 62 pilot. I think that what I call them. But I do have a set of #90 mains and #65 pilots. If I’m not making sense I’ll do my best to take a photo later.
