Exhaust head pipe color

[earlfor]

The chrome on the exhaust pipes on my GS at the exhaust port
has turned from all chrome to a slightly golden chrome. If they were turning blue, I would assume the mixtures were too lean, but as far as I know, slightly golded should indicate about optimum mixtures. Any opinions on this out there?

Mine are the same color. I've leaned my mix and enriched it to see if it would go away, but it stayed the same. So golden chrome it is. :?

from my experience, the gold color will indicate close to proper or a little rich, which is always better than too lean, for an air-cooled motor. Pull your plugs and look at them also, should be ashen gray color if perfect, and darker will indicate richer. Ride safe.

The exhaust pipes inlets on my 1980 GS1100E aquired a golden hue when I bought the bike new and it was spot on for performance. After getting it back on the road last year, the pipes remain the same colour as in 80-81.

The plugs are running pretty dark gray, but not sooty or fouling.
Maybe I've finally found optimum carb settings for this thing.
