You probably know you need lower temp thermostat at 5000 ft than at sea level ?
...That really doesn't make sense to me - not contesting it, just saying I don't understand.

Anyway, there's only one type of thermostat available for the bike. And that's the 82 Centigrade (179 Fahrenheit) one.

Also, why would running lean not be a problem if the bike doesn't overheat at highway speeds? Doesn't that just mean the air is cooling it down faster?
