Brenton,
I have the same experience after 11 years and 550 hrs. They were within 2.
Just change the oil and antifreeze each year.
Starts and runs like new.

Gig- I crimped every 40 mm to start. My first attempt was to no avail
also. 40mm seemed to work much better. Al Young 601XL.

To Dave and Brent, thanks for your Rotax compression info, I am installing a
912S on my 701 but was a little concerned after reading the maintenance
manual, have any of you on the list attended a Rotax 912 Owners/Maintenance course,
how useful would that be to a first time Rotax owner?

Listers. I just completed the first flight of 601XL C-GYXQ today. The
plane flew wonderfully. No real surprises other than: 1) I found aileron
control to require more force than I expected, 2) the oil temp was
getting close to max on the 912S even though it wasn't a warm day and I
wasn't maxing out the RPM by any means.
Can anyone offer typical temperature ranges for the 912S that you are
experiencing? I'm reading 185F on the CHT (liquid) and 260F on the oil
temp. I'd prefer to see the oil around 200F. I have an oil cooler
installed with air coming in from a Naca in the cowl. I know I can do a
better job of sealing the intake to the oil cooler, so I'll try that
next to see if that reduces the temps at all.

Coolant temps look good. The oil temp at 260f is hard to believe since you
were not running the motor hard. You need good negative pressure on the outflow
side of the oil cooler. The NACA duct really is not intended for high presure
ram air and will not perform properly unless the air is sucked through the oil
cooler. Congrats on the first flight. I bet the smiles are still there hours
after ya landed.
