cylinder head temperatures
I started these days a 912 ul on my new coyote rans.
everything goes well except a cylinder head temperature.
the cylinder sensor n 3 (rear) indicates normal temperatures (80-90degress after 3 minutes, steady rise);
the cylinder n2 (front) rises up to 120 degrees then lowers to 100 then goes back to 120 then lowers to 100, etc;
is it normal, it is a use between 1800 and 3000 rpm and on the ground.
thank you in advance
