Re: Why did my pipe discolor so quickly?
Just a word of caution about the engine break-in period. Don't ride with the throttle wide open for extended periods of time for the first two or three tanks of fuel. Vary your speed going from a slow cruise to WOT then back to a cool down time. I'm not saying this is the cause of the heat affected area of your pipe but it can contribute to it if the engine is operated at full throttle for long stretches until after it has had a chance to properly seat the rings. Nougat is correct in that the Chinese chrome is not the best quality but even a good triple chrome plate will discolor after a period of time given enough heat. Enjoy your bike and ride safe. By the way, congratulations on your successful build.
