Jardine 4 to 2/ 77 GL
Hi All - picked up a 77 with Jardine exhaust. Pipes are extremely blue. Does this suggest a rich condition? thxs kenai

Jardines are single wall pipes and do tend to blue very easily. I had a set on a very well tuned 78 and they were blued significantly after just a few months. Check you plugs and see what they say before digging in.

Blue makes them beautiful, so if your plugs are good you are golden.

Re: Jardine 4 to 2/ 77 GL
In my experience blued single wall pipes are usually excessively rich while lean gives you a straw color, but imho nothing is absolute on pipe color.
I know from seeing many Keihin carb’d bikes ( g-wings, cb750’s, 1100’s etc and including Harleys) run on a dyno with a lambda sensor they all do the exact same thing with the stock Keihin’s. Very lean 15-16 to 1 a/f up to around 2000-2500 rpm (emission test point) at which point the secondary main comes In to play with the needle being raised out of the jet and the a/f ratio goes to somewhere between 10 - 12 to1,, pig rich ! Which is why you can add headers and such w/o worrying about jetting. That’s what I’ve actually seen !

This is a new bike and once it is started their is so much gas in the air your eyes water. Mass gas! Plugs were goopy definitely not lean and clean!
