Has anyone tried to make an adjustable cowl flap of some type? Considering my water and oil temps are low I'm wondering if this might be a nice adjustable solution for all weather/temps.

Can someone enlighten me as to what is a min except able water temp on the 912 is?

As for oil I've been told 180 F is acceptable as long as you get it up above 212 F every once in a while.

Thanks all...Lots to learn.
