Hey,
I am running a 38 idle jet and Main Jet is 162 for summer time trail riding. However, I have a FMF Gnarley exhaust (expansion chamber and pipe). Call Woody or Wheelsport and see what they say.
Hope that helps.

Hi,

For summer riding,my 2012 300 XC-W with original pipe has:

38 Pilot jet
NECK needle 3rd clip position (suzuki needle)
162 Main

I've tried other combo's but this is the best overall for me.

It depends how you want your 300 to feel. You can change it up a lot but playing with the jetting.
