Hey guys, new to the site, also new to the cycle world. I'm having a problem fouling plugs. A little background. Bought a 1975 cb750 (k2 I believe). Running straight headers w/pods. Plugs are fouling after about 1-2 miles. I believe it's running rich, black carbon. Tried running a hotter plug and have messed with the air mixture screws to no avail. I'm guessing I need to rejet down. A little insight would be greatly appreciated
