Sorry about another jetting post but i need to jet my bike quickly if possible. Its got a 145 main in it with stock needle, pilot. As far as mods it has an insane performance aluminium air box w/o lid and a twin air filter. My elevation is right around 3000 ft. I am getting an HMF s/o tomorrow and have a race on friday so i want to be dialed in and just want others opinions on jetting. Thanks
