Okay my friends, here's the problem.
'04 65 jetted real close, 40:1 fresh pre-mix, ran great. Started missing slightly on the top end of revs. Did the usual, plug, air cleaner, Etc. helped a little. Next ride, same altitude, temp, Etc. Missed more. Plug real black and a little oily. Next ride, missed real bad at mid to high revs. Power down, plug blacker and oilier. Any ideas? Stator, coil, ignitor, right side crank seal? I'm at a loss and due to domestic situation, have only limited time to trouble shoot. Riding is my young sons quality time with Dad and I need some ideas from people who have had this problem so we can ride.
Any and all ideas would be appreciated.
