When I lock up the back tire with the rear brake, If I let the rear end slide to my right, there is a metal clanking sound. It only does it when i let the rear end slide to the right. If I make it drift to the left, it doesn't make any sound. Anyone have anidea what's making this noise?

 

are the main nuts tight on your axle

 

This sounds like a tightening issue if you ask me.

 

Chain?

 

youre drifting your bike on a normal basis?

 

you might need to adjust your chain. like DBEAU said.

 

I know when i lock up my brake the chain chatters... I thought that was normal. Am I wrong?

 

if you don't pull in the clutch the rear wheel can hop under engine braking, giving you a hammering feeling+sound from the back. I don't think this should be side-specific
