I recently installed a jet kit and K&N air filter on my quad and it is running great
but...

When the choke is all the way up it is reving high and when all the way down it almost kills, it is suposta do this or

1. are they the wrong jets

2. the needle screw is turned to much/little

3. the choke cable is on there wrong

4 anything else you can think of

thanks

 

It should idle fast with the choke on. But with the choke off it should idle normal. You need to adjust the idle mixture screw and the idle speed screw.
