I have a 2016 outty 850XT, Just now getting into all this belt stuff so stay with me here lol. I havent even got done breaking mine in yet but I will be going to harlen kentucky mid month. I’m wanting to take a spare belt with me. I have read so far that I think the Dayco Carbon is the best belt for me. My question is does anyone have a part number? Best place to buy them to have it within a week? Also my buddy has a 650XT, I think its an 09′, will this belt also work for his as a spare?
