Does anyone know where the air presure sensor is situated on the bike? Is it in the air filter inlet tract or just behind the fairing somewhere?

Air pressure sensor?
Afaik if its for Throttle Bodies (and probably carbs as well) there's a MAP (vaccume) sensor mounted on the TB assembly with little pipes going
to each branch of the inlet manifold.
Or there's a temperature sensor presumably on part of the inlet/air filter ducting.
But have never heard of an air pressure sensor as such, presumably that would only be to measure altitude and adjust for the air thinning at height
which i'm pretty sure the R1 wouldn't have.
Which model R1 do you have?? There are a couple of air pressure sensors on the 04 - 06 version anyway.
On the 02/03 injected engine the sensor is in the airbox so I mounted mine into the backplate of my panel filter.

Its an '06. There's a temp sensor in the air box. A manifold air presure sensor screwed to the fuel rail and with a vac' pipe to the
throttle bodies. Then there's an atmospheric presure sensor (same part No as MAP sensor) that was...where?
I thought it just read from behind the fairing/under the seat. Then I thought, how does the ECU deal with fueling when ram air comes into effect? Does
the sensor read from the air filter tract where it would see the presure change?
I've had another look at the service manual and its not that clever. It's shown behind the saddle. Cheers guys.

The atmospheric pressure sensor should be mounted away from any airflow if possible as it is affected only by altitude.
On the ZX12R, it is positioned underneath the rear seat cover. I would imagine it is in a similar location on most bikes.
