My pipes are turning blue !!

another cost adder to our already overpriced motor fuel.

You ought to try paying UK prices, then you would appreciate your cheap fuel!

We are currently at $3.78/US gallon for our premium 93 octane fuel....For us nice folks here in the colonies, that is a record price for motor fuel...diesel fuel is currently at $4.07/US gallon...again, another record high price for motor fuel. There is plenty of blame to go around for our high prices...the forecast is for fuel to go down late summer...about the same time we begin bombing Iran's nuclear facility.

If you had entitled your post: "Why have my pipes have turned blue" then you would have had replies like, "It means that the engine has been running".
The pipes on all of the 1100 and 1150 series bikes will blue within a short time. My RT has the pipes blued for the first 10" or so and then a slightly brown hue for the next 6".
If yours are blued to the cat-converter, then maybe I don't ride my RT hard enough.
You can polish out the blue only to have it return on the next ride.
