Sounds like a hose is collapsing on you. Have you checked the tank vent for a partial obstuction. Try running motor on a seperate line/tank and see if that solves the problem. Happened to a friend of mine and it turned out the inside of the fuel hose was collapsing under high RPM's. Check the obvious/cheapest things first.

Oh yeah, forgot to mention, checked the tank vent - no obstruction whatsoever.
I agree, I should run it on a separate tank and see what happens. If it were a line collapsing it seems I would have trouble priming the ball while my buddy is running it above 4500? I'm able to keep up and it doesn't "feel" like a fuel line problem.

I saw the fuel line that collapsed on my friend after he replaced it. It seemd like the fuel line had a bladder in it (a hose within a hose). some parts were still intact while a small portion of it was not. That was the part that gave him the problem. Running on a seperate line/tank is the way to go now to eliminate engine itself as being the problem. Good luck!!!!!!

Thanks Cam! I agree with you. I'll do that this evening.
For now, let's pretend I do that and still have the problem - what comes next?

Where are all of the internet mechanics? Taking the day off? Hello? If I don't hear back soon I'm going to go by the Honda dealership to look see about a new motor.
