Replacement for GPz

Just my $0.02 worth about altitude.  It is amazing how quickly my GPZ loses
power as I go up in altitude.  With a passenger on the road to Mount Evans I
thought I was running out of gas and actually switched to reserve only to
find it was just the lack of power from no air and too rich a mixture.  I
think I've really appreciated about my CBR600RR is that although it also
loses some power, due to it's fuel injection, it doesn't lose as much on
that same road.  Life in the mountains remains interesting.

No offense to Don, but I concur with Mr. Daniels' impressions of the ZZR. It
did seem to have a little more torque but the ride felt harsh and buzzy to
me. There didn't seem to be any real noticeable difference in power between
the GPZ and the ZZR other than the afore-mentioned slight increase in
torque. After riding the ZZR for a few hours, it felt good to get back on
the GPZ. Much smoother ride and more than enough power to keep up, though
the ZZR's suspension was better set up for the corners. Just my 2 cents.
