So I am concerned. Can anyone give me any pointers? I recently did a 520 swap on my F4i. So I took the bolt for the front sprocket off(it came off pretty easy, compared to other bikes I've worked on) and then I put the new one on. When I tightened the bolt back down, there was some play in the sprocket left and right. Like, the bolt was tight, and I could move the sprocket left and right no the splines, like, half a millimeter. I was concerned, so I put the stock one back on, and it had the same play. Is that just normal? Anybody had this problem before?

Thanks

 

yeah its gonna have a little play, not a TON but a little

 

since we're already on the subject of front sprocket....what should that front sprocket be torqued down to?

 

A few quick google searches are showing 40 ft\lb.

hopefully someone can confirm this, I don't have access to my manual here at work.

 

Yeah, the Driven counter sprocket had a little play in it too. 40 ft./lbs. is correct torque.
