I went to the dealer and bought a new larger .170 jet. Runs great!so i just put installed the HMF on my 500. I thought that it would come with a few different jet sizes but it only came with the 165 size. I live at 1700ft should 165 be the right size? or do i need 170? Im going to tear into the carb tommarrow and put the jet in and adjust the a/f 2.5 turns out. does that sound right? btw the hmf sounds great!!!!!!
