Question Intermittent Rattle

I have a 2001 600 XCSP and when I started it up the other day I heard what can best be described as a metal rattle. It doesn't sound like anything directly in the engine and the sled does run fine when I ride it. I only notice it when it's idling, but imagine it happens other times but I just don't hear it. I talked to someone who said it could be coming from the primary clutch weights, but to me it sounds like it's on the opposite side. (Exhaust, chain case, etc.) I realize this is a very obscure problem, but any ideas/help would be appreciated. Could it be as serious as a bearing problem, or is it more likely something that's just loose and giving me the metal rattling sound? Thanks in advance.

Check heat shield clamps on the pipe. They loosen up after a while and the clamps rattle on the heat shield. Also the sway bar slides will rattle in the trailing arm. Grab a hold of the swaybar and put pressure on the slide. If it stops then its just the slides.

Park the sled and rev the motor up to, but not quite at, the point where the clutch engages and let the throttle go. Does it make the noise as the motor speed is slowing down? Sort of a metal-on-metal knock, single knocks, evenly spaced?

do you mean the intrigal parts were loose or do you mean the whole recoil assembily was loose on the motor?

no not evenly spaced, not a knock, more like, how do i say, "ting ta ting ting ting." kind of the way a 2stroke idle sounds different than a 4 stroke idle. you know, 4 stroke is a rational "pop pop pop pop..." this sounds more like was suggested before, something like the heat shield is loose, just cant seam to be able to find it yet.

Complete recoil assembly came loose on the motor. Took a jump, heard something, pulled into my yeard, and voila, rattle like crazy. Had to get new assembly as it broke a chunk off. What happens when you try and be a SX racer but not even close

Could well be bad gas. My 02 Edge has two "run" positions on the ignition. They are intended to be used in alignment with the octane of the fuel you're using and change the timing on the motor. When the fuel is going bad, the octane drops. I need to switch it to the "regular" setting at that point to eliminate the knock from the motor (which is what the noise is).
