Jetting on "08

[latina]

I recently add the HMF exhaust slip on only on my '08 TRX 450R and i got the Jets as well too...It came with two small pieces , i know what is one ( the jet ) but the second piece dont know what is it and where it goes....Help!!!:confused:

One is the main jet and the other one is probably a pilot jet. It also goes in the carb. Can you post a picture?
