Sorry if this question has been asked before...search was unproductive.

Looked at a bike for Flying Jlady on Sunday. Great fit, super condition. It's a 2002 Yamaha V-Star Silverado. Has windshield, bags boards no dents or scrapes. Price is at the high end of normal. Here's my concern:

The head pipe for the forward cylinder is a beautiful shade of gold for the first 8 inches. I've seen blue pipes, but haven't noticed "yellow" ones. This is a single carb bike, air/oil cooled with ~6k miles.

Is this a sign of improper mixture, valve adjustment or what?

Thanks for any help.

I believe gold is just an early version of blue. If left unchecked, it will turn blue. You should be able to clean the pipes with Blue Job or some other cleaner at this point, but you should adjust your mixture. I believe blueing is a sign of you pipes getting too hot (lean mixture), but, hopefully, someone with more knowledge will chime in.

I agree the yellow/blue is just a sign of a lean mixture. My 04 did the same thing until I debaffled and rejetted, along with the K+N filter. The stealer even told me the same thing, it has totally stopped since the mods.
Hope this helps. Scott
