Hey,

Just noticed one of the gaskets that connects the rear muffler to the balance pipe seems to be leaking a bit of exhaust.
Just wondering how bad this is and how urgently I should be replacing it?

No biggie, very common. If your bike still has warranty you can have the dealer change it for free. Otherwise if your near me go buy a gasket and I'll fit it for you no charge.
