Hmmmmm...

Weird.....

You know I never had to crank a machine so far up in the rev band for so long, but I heard a noise like a second vibration, (Im thinking crankshaft) up around 9 or 10k. If I keep it there, its like a constant nummmmmm......nummmmmm.... but not in tune with the engine. Like secondary. I was going to call somebody at Cycle Sports but they would probably not know what I am talking about... Maybe its partial to the 600's. Who knows. I do know its directly under the tank. Maybe its valve float... Its gotta be valve float.... No. Honda wouldnt do that on a machine that rev's to 14k would they?
I thought of chain..... nope. I thought of crankshaft.... probably not. I thought of intake niose.... maybe.
Who knows, I might be able to work this out by myself...
At least I have a start.
Didnt mean to ignore your problem, but I was trying to make a connection.....
