Great product

This is definitely worth getting, installed on my 2012 Ninja 250r and wow! No more hesitation, great throttle response and more power in the low to mid rpm's.

Q: I have a two 1982 Yamaha XJ650 I am rebuilding. One I am leaving stock air filter on and adding a 4 into 1 header. What stage kit would you think I need to install. The other XJ650 I am going to put on pods and an open exhaust what stage would it need.

A: There are 3 different XJ650 models from 1982. Enter you bike into our website to ensure proper fit but it looks like the only kit that will fit is the 1&3. These come in a package together. Dynojet Stage 1 & 3 Jet Kit Part # 4103

A: It does not modify the air box. This is just a jet kit for the carburetor itself. All air box modifications will be a separate modification.
Q: What are the main jet sizes

A: If you have a stock motor, cams, pistons and porting the Stage 2 will be better suited for your application.

Q: May have the wrong main jets
Over 6 years ago
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.

A: 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.
