Hondabuster makes a great point, nobody wants to have discolored head pipes on their roadbike. Harleys are no exception here, as these things are installed as much for looks/sound as they are for power. You don't find many chromed 4 stroke pipes for the atv/dirtbike crowd for a reason I think. Stainless is just easier to clean and is much more resistant to corrosion/elements. I guess about the only advice I have left for you is not to buy one of these if you can't get your mind around the glowing header. Even the fuel injected models do it, this is a condition seperate from jetting issues. It is rare to hear of one of these modern 4 strokes burning a piston. Quads have been running this generation motor four years now, the bikes significantly longer and there just isn't an epidemic of engines melting down. One thing you could do is install a bigger radiator and some engine ice or something, but the reality of it is that these quads were designed to run and run fast. Pretty much EVERYTHING about the YFZ works better at speed, not just the cooling system. If you want a tractor/sport quad, buy a 300EX and don't ever upgrade to a modern style thin wall header.

 

Ahh OK Scooter. I think I get the drift on these particular engine types.
Only one purpose machine, Go fast , competition racing, etc etc etc...
But if you want a leasure time or plow and stop for a beer the machine is not to be left alone idling.
All go no time to stop and shoot the breeze type machine.
I guess that solves it all in a nut shell.

 

Yes you are right, if you want a plow puller or want to go slow enough to smell the flowers as you ride buy a utility quad of some sort, they are quiet, the exhuast is hidden away from you so you don't feel it. Although they too do get warm, they don't put out the heat to the rider like the race bike's do.
