I was about to say exactly the same. Indeed if the sensor is now close to
the airstream then it will be subjected to cooling air and will underread
considerably. The mod would make sense for the oil PRESSURE sensor, but not
for the oil TEMPERATURE sensor.

Thanks for the info Roger. It definitely sounds like it is the sender (will
find out for sure tomorrow).
However, like Richard and Fred I am a little confused as your description
suggests the new arrangement means the sender is mounted in a pipe which is
a dead end which would have little or no oil circulating past it. Or is the
pipe somehow forming part of the oil circulation system.
I think my preferred choice would be to mount the sender in the return line
from the bottom of the crank casing (would need a metal block to screw into)
where I assume it would be at its hottest. An easier fix might be to bolt it
into the oil tank somewhere. This would be simpler, and there would be less
vibration. Possibly a hole tapped into the centre of the oil tank drain plug
would work.
Still, if you have an approved mod then I am sure these issues have been
carefully considered and there is no point in reinventing the wheel etc etc
!!!

I get mine from a local stables (where my daughter rides - they use them
once only to administer Equipalazone); I just rinse them out. They are 20
ml.
I mix in the cup first, then use a syringe for fiddly applications - just
pour straight from the cup (or dab with the stirring stick) for normal
layups.

Hi,
Probably a silly question ... I have just purchased my electric scales for
measuring out my resin, and I am looking for syringes, can anyone in the UK
recommend a supplier or can point me in the direction of a store where they
might be sold? Also what sort of size is best?

I believe Rotax is sensing cooled oil -- not the hot stuff in the return line nor
similar in the tank, and they set the redline temp premised upon the effect
of mounting in the engine block where they do. I would caution against any mod
which cannot verify the Rotax redline temp is still valid, or proper testing
to set a new value. So far we have one reported instance of a complete failure
only alleged due to vibration. A google search I did turns up nothing else,
nor is there a service bulletin. If vibration can fail the sensor, then the
temp instrument will go blooey, so then just replace it. A significant cause
of homebuilt accidents is this type of experimentation, resulting in doing things
in ways not seen on production aircraft for presumably valid reason.
