Well, I don't mean to critisize, but most people don't know how to read plugs. If you run the bike and then idle in to a stop, then pull the plugs and try to read them, it means nothing at all regarging how the engine was running when it was under power. They should read very rich under those circumstances. The correct way to read plugs, is to run the engine under load at medium to high power settings for at least 30 seconds to a minute. Then without rolling off the throttle, kill the engine, pull in the clutch and roll to a stop. Very hard to do on a street bike, but the only way plug readings really mean anything. You can do the same thing on a dyno, but not on a city street. With that said, I'd go right by the S&S carb set-up instructions. Its free on line from S&S and is very good.
