I use PJ Motorsports for Keihin/Mikuni carburetor jets/parts, etc. Go to pjmotorsports.com But if your machine has a "Kymco" carburetor, you may find a Keihin part will fit, but it might not. Then you'll have to find a Kymco parts supplier. Although many Kawasaki ATVs have Kymco motors, not all of them have Kymco carburetors. Good luck!
