I have a 1999 polaris explorer 400 2 stroke. Trying to find a carb for it. And not the Chinese knock offs. The original Mikuni is gone. I am wondering what yr carbs are the same??? Different part#s for different yrs. If its just the jetting that changed? And that made the part #s change. Just looking for info. Cant seem to find much on that. If you go by the chinese stuff Some yrs are the same. But I dont want to use those carbs, as the jetting is not correct nor can you get the correct jets for them. Mikuni jets do not work in all of them. Different threads.

 

Mikuni carburetors can vary from year to year, even if the models are similar. Polaris models from other years may share carburetors, but it is essential to verify the exact part number. Sometimes the differences can be related to jets, settings, or year-specific features.
