12190
These main jets fit the 99cc Predator carburetors. Also fit some of the 79cc Predator carburetors. You must measure your stock jet. If the threads are .194"/4.9mm these jets will work. If the threads are .154"/3.9mm you need p/n 12200. Choose from the following sizes: 70, 72, 75, 85, 88 & 90. After installing a high flow air filter we are using a #80. We use an #82 in our reworked carburetor.
