Hey Mike,
You might want to try a set of new plugs and start from there.
How new is the K&N filter. How much oil is in it?
Sounds like your set up is fine though. Not sure why the plugs might be a bit black. They should clear up on the highway.
Let me know when you pass through on your way back. Java at the local Tim Hortons Angels hangout
PS - Watch out for bears. Saw 2 on the highway from Sudbury today.
