I suspect lots of idle time (standing still) where the heat can't dissipate properly, may be more likely to cause blue pipes than riding hard.
All the bikes at the MSF Course I attended had "bluing" pipes to some degree (lots of standing idle time). But most of the same models on the street, I noticed, do not.
It's just a theory, but seems to apply (I'm sure other factors are invoved too). Patrick
