    525 XC Knocking like hell.

    Hi everyone! Been forever since I`ve been on here.

    A friend of mine contacted me with an opportunity to pick up a very nice 525XC the other day, at $1650 I jumped on it. Its only got one issue, a knock, a loud knock. It goes away when put into gear, wondering if anyone has any insight as to what could be causing it/where to look. I have a video but can't figure out how to attach it.

    Since it goes away I wonder if the primary nut backed off of the crankshaft, or something in the clutch? Have to tear it down to find out, but I'd start with pulling that side cover.

    It's the primary nut I'd bet.

    I would guess the primary nut too. I got my 450 xc with very low hours and always heard a wierd sound and it got worse and turned into a knock. I pulled the clutch cover and sure enough spun the nut off by hand. Easy fix if thats it.

    You guys are awesome! 20 minute fix and I've got a clean, perfect running 525 for under 2 grand. Apparently it wasnt quite as thankful as I am because it decided to chuck my poor ass for a loop on its maiden voyage last night!
