Put in the Hot Seat high flow intake with the K&N air filter and they suggested the 170 main jet. Well way to rich, went and bought some different sizes and couldnt find the right fit. Polaris says that the Le comes with a 150 main but when i took it out it size was a 47.5. What going on? Any suggestions would help thanks.

 

It sounds like you are looking at the wrong jet. A 47.5 is the pilot jet, not the main. There should be 3 jets, 2 small ones (pilot and starter jet) and 1 longer one (main). Check and change the longer one...

Here is a good site and a good illustration for you for reference...

You could actually change the pilot jet to a 50, and the main to around a 167.5 is what I'd suggest(but might need to go even lower).......and the needle should be around the 4th clip(depending).
