just wondering what little thngs i can do to remedy this problem. I am thinking hotter plug, or adjust more air in carbs. I have a 1973 cb 750 k four into 2 pipes. Just got it going recently. It has run but not good, so i put new plugs in it started better. Then adjusted carbs. It runs like a bike no hesitation nw. So ill try clean all plugs and run the bike again to see what kind of reading i get. If i get the same carbon, ill need some help on what to do. Thanks
