On a new to me pro 1200 the forward plug showed no sign of wear (ie brown color) after running a full tank of gas. Cleaned jets on all three carbs, changed plugs again, compression 140 on all three cylinders, plug has spark when removed and lying on cylinder head.
Also ran motor for a short time with only front plug connected.
Should I ride it.
