Blue spot on right pipe...

[MotoGoosy]

Right at the bottom bend.  Only on the right pipe.  Getting old, can't remember what that means.  Rich or lean?

Lean , EV should have dbl wall pipes so you may have a crack or hole on the inner part.

Yeah , caused by all of the horrible vibration  ~;

I don't know.I have the same thing . You'd think you would have a lot of responses on this.I've asked questions before about blue pipes and no one seems to give advice.You get stuff like "blue pipes are beautiful".

I have blue on the same spot on my '13 Stone (bottom bend).  Don't have any info, but yours isnt alone.

It's a clear indication of a problem.  Right at the bottom bend, an oval blue burn spot, only on the right pipe, just had the TBs synced.  Bike has a little over 10k miles.
