Hey I have a 2008 ltz 400 with a full pro circuit t4 exhaust and I need help getting it jetted I’m in about 1,200 elevation above sea level just seeing if anyone can help

With a yoshi slip on at lit the same elevation I have a 165 main but I forget the pilot so you may go with a 170-175

I would start with a 160.
