Rode out tonight about 30 miles on the lake. Hard and fast, but not outrageous. 70 mph cruise and occasionally 100mph bursts.

Now, the sled after a little bit of idling (2 minutes) I took off and it would not rev past 6000-7000. Right to the bar it was stuck there. Jiggled the plug wires, checked for leaks, over heating (it was 3 degrees F), but nothng looked array. Took off again, and it started to bobble, then slowly reved past, and seemed to run OK.

Got it home, saw the #3 cylinder had black deposit around the valve cover (the others did not) where the coil seated in the cover, and the plug boot/coil had a bunch of white around it. All plugs looked fine. I thought maybe it was arcing funny, so I cleaned everything, moved the coil to the #1 cyl, and went for a ride.

Appears to be OK, but wanted an opinion. Going on my big yearly trip on Sat, and dont want to spend it at a dealer up north.
 
could have been missing because of carbon buildup around coils. clean all 4 with carb or brake cleaner inside and out, and make sure they are firmly seated down on plugs when done. ;)!
