engine rpm

[RJ2112]

Since nobody has said this yet, here goes. I have been told numerous times that you are running an engine efficiently when it is anywhere below 1/2 the RPMs that redline is located, 7k for the FZ6. this means that you are in the "economical" area. Anywhere <3/4 redline, or <10,500 RPM is not "abusive". so i'd say if you're under 10k you should be fine.

If you operate a motor at 85% of redline (instead of constantly on the redline), you will more than double it's service life. 75% of redline will effectively double that again.
