WR426 Engine Rattle?

There is a loud knock or rattle at low speeds that is of no concern. The chain slaps on the top of the chain guide by the swingarm pivot and can be very loud at times. This is usually at light throttle positions when the chain goes slack and then snaps back tight.
A softer guide pad will be less loud but will wear out much faster. After a while you just quit noticing it.
Hope thats all it is.

Is this your first bike?
When my 01wr did the chain slap rattle it reminded me of my old Husaberg, Ktm, Husky...
Lugging it definetly makes more noise but it didn't come from the engine.
Forgive my condecending note, I thought all bikes did this when you are tired, hanging on, just trying to get up that next hill without grabbing a gear.
BTW, guys behind me said hey man your bikes rattling...
Ty Davis sells different chain buffer plastic, maybe this is why...

Anyway, I only notice it when the exhuast is corked; I just uncorked the bike and now I can't hear it or anything else.....
