WTF is this!?!?! - 5/8/2008 9:03:14 AM    benjiboy   Posts: 43 Joined: 12/13/2007 Status: offline The bike is down for some TLC and a tune up and when removing the front sprocket cover I found this mess!!  It looks like metal shavings mixed in with the chain grease but why the metal shavings? They can only be coming from the sprocket but is there an underlying problem to this symptom? http://i274.photobucket.com/albums/jj242/benjivboy/IMG00042.jpg   http://i274.photobucket.com/albums/jj242/benjivboy/IMG00040.jpg   http://i274.photobucket.com/albums/jj242/benjivboy/IMG00038.jpg < Message edited by benjiboy -- 5/8/2008 9:11:40 AM > Post #: 1

Plus, I found a little play in the sprocket even though the bolt is tight. How difficult is it to replace the front sprocket? (in reply to lonewolfcbr) Post #: 3

Then pull the old sprocket off, slide the new one on, replace the bolt and torque it to spec. (in reply to benjiboy) Post #: 4

When you get the sprocket off, check behind the sprocket and everything around it, and look along the chain lines to see if anything is being chewed up. _____________________________ I intend to live forever. So far, so good. (in reply to lonewolfcbr) Post #: 8

Also, anyone care to throw up some links to motorcycle parts sites I can purchase a sprocket from? (in reply to Hershey) Post #: 9

RE: WTF is this!?!?! - 5/8/2008 1:49:52 PM    elmer Posts: 422 Joined: 12/9/2006 Status: offline Lonewolf, you needed to put it in a higher gear than first in order to loosen the nut, otherwise yes, that will turn the engine over. (in reply to lonewolfcbr) Post #: 11

The weight of the bike will keep anything from spinning. If you have an impact gun it will pop off with the bike on the stand with little trouble. (in reply to lonewolfcbr) Post #: 13
