I ordered this kit for the ninja 250r 09 and I am not sure if I am doing something wrong or I have received the wrong yets even though there is a manual for the ninja 25r in the kit. The main jets do not screw in place where the old ones were. I believe the jets I have are smaller than the ones I am supposed to have. I have uploaded a few pictures to demonstrate that I am unable to screw in the main jets. I have also uploaded the manual stating it is for the ninja 250r. Thank you for the help in advance.

The main jet is supposed to unscrew out of the end of the emulsion tube( the long tube that came out of the carburetor). Once that jet is unscrewed the new main jet is installed in the emulsion tube. The emulsion tube is not to be replaced and will need to remain in the carburetor. with just the old jet removed and the emulsion tube re-installed in the carburetor the jets should fit.
