So I'm about 400 mi in on my 2022 and started noticing a burning smell. Upon inspection, noticed something running down the muffler. I pulled the side cover and it seems to be coming from one of the bolts from the heat shield. See picture. It's as if there's a piece of plastic in the area of the bolt that is melted and running down the muffler.

Anybody else experience this?

Things on your bike may smell like they’re burning when new. Make sure your coolant, oil level, & battery are secure and ride on.
As long as it’s not on fire, don’t worry about it.

I'm familiar with that ... like the smell of assembly lube etc burning off when the bike is started up when new. This is different: It's a burnt plastic smell and it is coming from whatever is running down the muffler. My speculation is that there is a plastic washer on the back side of the muffler heat shield that is melting. Why it took 400ish miles to happen I can't say for sure.

I'll just guess that the Thailand assembly plant 'accidentally' installed some sort of plastic washer under the heat shield rather than a Heat Insulator washer!

I wonder 'WHY' there would be 2 different part numbers for those washers? They both use 6mm screws.
Maybe they should have used 2 of the thick ones?

Even on my Gen1, excessive exhaust heat was reported by some which could warp the plastic trim piece on the right side. I used a metal tape (dryer vent tape?) on the exhaust underneath the right side plastic, Have never had an issue. Although I have always left exhaust stock. If you are running an aftermarket pipe, more open breathing can be leaner, more peppy, and (pun intended) Hot tip - Hotter. maybe use half a roll of tape. (no offense to pipe guys, I am sure they sound cool . . . ) L6
