i did another test run today and checked my plugs rite away and they were silverish brown. is that normal or does that mean im running a little lean? i have i/h/e, hi-flow cat, cam gears, ingition. would putting the 65 shot fuel jet in be ok? running a little rich is better than running a little lean rite? isnt it better and faster to have more fuel anyway? i might put in the 65 fuel jet if its better than sticking with the 55.
