out of interest what high needle setting do you guys run with the dominator ? been running mine for a few tanks and have checked the plug and have had to back it out a 1/4 turn going on the plug color, don't want to heat seize the thing now. looks a little like this

I run mine a little rich too. My plugs look like that as well. I have never fouled a plug. I could lean out for slightly more power or speed but I love playing with a relaxed it don't matter attitude. Actually it is real close to stock I think its 11/2 on both or close to it. It really depends on the engine and carb and set up so taking someones settings and trying it on yours should only be a start if not running. I think you have a good color, the other thing that will color a plug is the type of oil you use. I can go through one or two tanks before I can get any type of color on my plugs using Amsoil.:(
 
well i managed to get out briefly in between rain showers and can report that it has made a big difference to the loudness of the dominator it sounds more like my mates samba now, and I am pleased with the results. I have not noticed any drop off of power either if any thing it seems faster, this can't be the case but who knows.
