Hi, Can someone explain why the pipes on the bonnie turn blue? I was told is was due to bad tuning. Thanks!

They all do it, its mostly due to the god awful AI system....My Bonnie wears her bluing with pride.

I'm sure someone will give a better explanation, but it's not due to bad tuning. The AI system does contribute, although my AI has been disconnected since day 1 and I've got lots of blueing. Tha Americas and Speedmasters don't show it so much, because they have double-walled pipes up to the exhaust ports. I believe any chromed pipe will blue due to the exhaust heat, which is why so many aftermarket pipes are double-walled or heat-shielded.

Embrace the blueing, man - it's part of the soul that makes Triumph cooler than the others.

Now, will one of you rocket surgeons please give a better technical answer?

The only pipes that don't blue are pipes on a bike that isn't ridden!

After 6500 mi on my TBA the pipes show about 1/2" of blue. No way to speed up the blueing, **it happens.

They turn blue because they get hot and they are single-wall. Removing the AI does not eliminate this. Most of us have blue and gold pipes to a greater or lesser degree.

I had a Harley guy start telling me all the great stuff to get rid of bluing until I interrupted him with...... BUT I paid extra for that color! He walked off scratching his head
