Does this indicate valves are out of spec on front jug? I've inspected the plugs again. Rear cylinder looks good to me, possibly a little on the lean side. Couldn't tell with stock pipes, but once i went w/2 into 2 pipes; easy to the see that the front is the culprit.
Any suggestions to what I need too address; greatly appreciated.
I don't have a fuel manager installed. It's an '02 c
The first 6 inches of the front pipe yellow'd from the front cylinder, probably within the first 50 miles.
