Pilot Screw Adjustments

What function does the Pilot Screw do in the teryx carbs?

Is it a Idle mixture adjustment or a part throttle adjustment or what?

I no expert in carbs, but I think that there is a Pilot Jet and Idle Mixture screw. Pilot Jet is one needle sets in.

I could not find a idle mixture adjustment in the teryx service manual. The manual shows a pilot screw adjustment but does not say what it is for or what it does.

The pilot jet (not sure on the screw) Is for idle fuel delivery I believe but I am not expert. I know when jetting I usually don't mess with a pilot jet. I bet Todd from Hunterworks will chime in he seems to be the expert on carbs and such.

No expert on carbs just spent a lot time screwing up.

The pilot screw adjustment can be one of two things. I believe when they call it a pilot screw it adjust fuel for idle.

You accomplish the same thing with a air mixture screw but you do it with air instead of fuel and it is still for idle only.

Some carbs use a pilot adjust for idle and some use a air adjustment.

The "pilot" screw is on the bottom of the carb with a brass plug over it. Go over to my website and watch the install video for the Teryx carb kit to see how to remove it and then adjust it.

Why do you think you need to adjust it?

Todd,
I've been following your posts on your carb kits and after installing the dynatec CDI I noticed the same rough idle and miss at idle when cold or warming up at a slow idle. Just wondered if a slight ajustment might cure this problem.

I realize the carb kit you sell may take of this problem and gain more power. Thanks for your replies.

Lenf,

If your only problem is idle then a adjustment may do it. My opinion is jaded but the kit will do it and it will definitely help your performance.

Neverenough, thanks!!

pilot screw adjustment

Go to Nyroc's ATV info website. In the tech articles for kawasakis, there is an article on the proper way to set the pilot screws. Those boys know there stuff! That site has kept my 02 prairie in great shape all these years and saved me quite a bit of money. All kawi v-twins respond pretty much the same. The carbs have changed over the years but are still basically the same

Here is a pretty good carb tuning article at the HighLifter Forum.

I have seen the Nyroc one but can't seem to find it again right now. I also like the Nyroc site.
