Yes.... this is exactly that I would think if it where anyone else's bike. What puzzles me is that this is a change in my bike's M.O.
But, it does make sense.

I'll wait for it again, but like I mentioned, it "feels" like the RPM is literally as high as it says, although if that where true, it SHOULDN'T go that slow.... for mechanical reasons.... so I guess it can't be true. But it does seem to loose the power to increase. If it were reading artificially low, I wonder if it would hit the REV limiter early.
