I'm no carb expert. My spark plugs are always black and have been for the past year and a half since I had the carbs out. I have not checked compression yet, it could be leaking rings or whatever causing the black soot. The bike runs fine, I get OK mileage, not really any problems now.

What things are possible to do to 'lean' the carb system. I don't remember how many turns out on the idle mixture screws, but I could easily change that. The float heights were triple checked, I know they are dead on. I have never seen any nice brown plugs, always black. I have the normal NGKs in there, just put in a new set a couple weeks ago.

I could just leave it alone if it works, but I would like to know what if any adjustments I can do. I don't mind tweaking a little?

Try turning the idle mix screws in 1/2 turn and run it then check the plugs again. Make sure your air filter is clean and the choke is opening all the way.

One way to check to see if the rich mixture is at idle or at high speed is to take the bike out for a fast highway run then kill the engine and coast to a stop. Pull a plug and have a look. If it's black, it's not just a rich idle mixture.
