I'm confused, how can the elevation you are at change?

Yep 15% at 5000 feet
18% at 6000 feet
20.25% at 6750 feet
Most of the morning runs are around a best of 5500 feet and the afternoon runs as much of 7200 feet

Last year when ran first thing in the morning on the thirdrun we crashed and it was 5565 feet. The 2nd run at 3:30 in the afternoon it was 7223 feet.

Ah, interesting, I never thought about barometric pressure

The actual altitude doesn’t but the density of the altitude that is effected by the weather does. Hot and humid days will significantly raise the density of altitude. This effects small piston aircraft too when trying to take off. The Bonneville Salt Flats is about 4236 feet above sea level but on hot muggy day the air becomes thinner or less dense so the salt flats air becomes equivalent to a higher elevation standard atmosphere.

Years ago used to use a density meter to help figure out jet changes on race cars.

Yes the owner has the limiter removed. The bike was only running about 5600 rpm at the GPS 144 mph (speedometer 151 mph) according to the Dentist guy from Nashville....do you know him?

The road was rough with lots of elevation changes and a few badly filled in pot holes and the bike was rock solid so I'm happy.

I'm sure the bike will do considerably better on a longer course and when I don't need to roll off the throttle a few times.

This was a very peaceful and serene ride it will get much more energetic.

mine topped out at 236km in standard trim.
after removing limiter it gets to 236 in 5th gear and onto 255 in 6th. wind resistance and lack of aero is hold in back.

update- cooler temperatures with a slight tail wind and more road. 270kmph (6000rpm) berried behind the flyscreen, essentially laying on the tank.
