Topic: Drive Chain Rubbing

[The Lone Builder]

While checking over the bike at teh end of yesterday’s run, I noticed this pattern on the chain. It is just the grease that’s come off, there is no metal removal - yet.

Anyone got any thoughts on what ot might be rubbing against? I don’t really want to start taking covers off to try to locate it.

From picture it looks as right side of chain, check area around front sprocket if it is not rubbing against case

Is the chainguard secure? My own hi mile bike busted the rear mounting tab on the swing arm and the chainguard brace got sliced in two from rubbing. The front chainguard mount held it in place. This part is shown on the K2 fiche but not listed. You may also have the case protector near the front sprocket.

 Pretty quick and easy to pop off the countershaft sprocket cover to see if there is any signs of rubbing there like witness marks in the crud and if not work downstream around the chainguard/swingarm/centerstand area.

The tight curve to the marks suggests something in the vicinity of the front sprocket, it's a tighter radius than the rear.

That chain and sproket look orrible and worn to me

Check your lower shock mount bolt - if it's too long it could touch the chain as the shock compresses.

+1 good eye on that Mark M
...and good on you Loner and best wishes for a safe and complete trip.

Check for a bent chain guard at or near the engine end of it. It might also be a too-long 6mm bolt there that holds the chainguard onto the swingarm.
