2001 Trail Boss 325 popping noise from chain/ sprocket area

[copedaddy]

My wife has a well used 325 Trail Boss and recently she noticed there is a distinct rhythmic clicking or popping noise that sounds like its coming from the chain/ sprocket area. Increases with speed and happens in fwd or reverse.

I jacked up the rear of the quad and rotated the tires and there is no sound when the drivetrain is unloaded. Any suggestions on what this could be or how to troubleshoot? Im new to 4-wheelers, so this might be something pretty simple but I just dont have much experience working with them.

Would appreciate any help or suggestions

first guess would be a chain adjustment, then would be the bearings are shot in the rear carrier

My first quess would be bearings ! Is the rear a straight axle ? If it is jack it up and see if ur tires move up &down or Side to side !

Yeah, its a chain drive sold axle. Ill jack it up and see if I there is any movement. The sprockets and chain dont look worn but looks like its adjusted pretty tight. Could it somehow be binding and popping free as it rotates?
