I looked into the "Hot Exhaust" symptom. After several hours of study I discovered it is a result of hot gasses being pumped thru it. Problem solved by keeping the key out of the ignition.

Other than that, if the header is blue, its time to jet the carb.

Yes, thank you Angry

The header is blued, the muffler is blued. I expect the pipe to be that hot, but the muffler baffles should dissipate the heat more than that, or at least it seems, especially compared to both of my friend's other bikes, which have much cooler mufflers(my muffler was still a frying pan minutes later, whereas I could touch the muffler on his honda within a minute or so).

I suspect white, way too white. The carb may not be delivering enough fuel. You may have a jet semi plugged off ? IDK, sounds good from here

Lean, it seems. As Justin said - check the plug, if white - put one size larger main jet first and test. If white again - trim the white washer a bit. Then some more. Then more...

Did anything get changed on the bike? Has it always run so hot? If its blue that far back, Id wonder if the exhaust valve isnt held open. Have you adjusted the valves recently? Are you sure the decomp solenoid isnt stuck?

Just got it, don't know, I haven't done the valves, I'll be sure to check the solenoid.

I was planning on replacing the spark plug anyway when I did a number of other repairs/mods, so I'll deal with the carb as necessary if it's running lean.

muffler gets hot enough to take the skin right off you.... ask me how I know...
It's normal, look at car mufflers.... ten feet back fron the engine and super hot... just normal...

It doesn't mean you're lean,... pipes can blue from running rich too... it just means you've been running bad or running hard...
Mine blued after I had the petcock problem,...

Still blue now,... I think it's pretty.... Huh

But car mufflers aren't baffled, motorcycle mufflers are.

As noted, it's not just the pipes (which is pretty normal, from everything I've seen and heard), but the muffler as well. It's pretty seriously blued. I had suspected it was running a bit lean, and the bluing built up over time, but that might not be the case.

I was planning on changing the plug anyway, so it's just another thing on the list of tune up/blank slate repairs to do with the new (old) bike.
