Your comment forced me to do some online digging. Now, let me tell you what I found, and what I THINK I understand.
There are TWO things happening in the 250 engine:
1. high compression, which CAN lead to pre-detonation
2. short-stroke, high-RPM engine; which needs a "fast burn" fuel
If I'm right, then we really NEED to use 87-octane in the Ninja to allow complete combustion in this fast turning engine. That is, UNLESS there's knock or ping, but that could be caused by other stuff (lean burn, internal carbon deposit, etc.) besides the Octane. Am I on the right track, here?
Maybe my "smoother running engine" has more to do with break-in than fuel, and I'm going to see what happens when I change back. I *MAY* still "waste my money" if it doesn't pan out, but that's a story for later.
I still think you owe us an apology for cussing. That just cheapens the board.

I paid $3.25 per gallon at Costco yesterday for 87 octane. Eesh. (n/t) — Alavan, Thu Apr 19, 2007 7:59 pm
