i know its a little out of our efi world but i need some help with my teryx. got the right jets in but how do i tune out a lean miss when i let out of the throttle? i know a lot of you have had carb bikes before. it only pops after getting on it and then letting off, oh and its dual carbs. thanks

I believe from the snowmobile days that raising the clip on the needles is what would fix that.

You're correct, usually I would put the clip in the center position then go riding and see how it felt at all throttle position then I would check the plug and if need be, I would adjust the clip either 1 notch up or down depending on the throttle response and plug. Don't forget to ride the bike at high rpm then shut it down then check the plug.

But I thought main jets are used when at WOT, needles in the middle and pilot on low???

put bigger pilots if they are the same as the brute force you will need 40-size 74 series. Im about positive they are i have them in stock if you need. they also dont have adjustable needels you need to shim them unless you install different needles like DJ

With the backfiring when letting off bigger pilots will help

What they said about richening up the pilot is dead on, but I would try the air/fuel screw first. I am not familair with the kaw carbs, but if you should be able to add more fuel by turning the fuel screw in............I think.....in or out, I am sure it is one or the other.

Stay away from your pilots! There is nothing wrong with them. I run a FST standard bore kit and still have the stock pilots. Richen your idle screws. You will have to pop the covers off of them to get to them. I dont know the extent of your mods but you might want to check into a Hunterworks jet kit. Also put a set of plenum rings on it. Kawasaki will NOT warranty your valves or topend after it goes down. TeryxHQ is the forum I belong to and has taught me alot. Get on there and check it out. If you want some more speed a Dyna non programmable cdi will get you another 5-8 mph and set your belt deflection tighter (usually removing the fatter of the two shims in the driven clutch) will help. PM me if you have any questions, I've got a lot of time in Kawie V twin motors

They can be finicky! Good luck with it and check out those plenum rings. Cheap insurance!
