Just started flying XP400 with EFII ignition and fuel
With only 9 hours on the engine and mineral oil,
I'm seeing from about 189 to 203 but its winter here temps have been 25-45
but that doesn't seem to be the driving factor at this point.
I'm guessing i'm running into the Vernatherm cycling at this point.
I agree with the previous comments. fly the engine and give it a chance to break in, your temps are fine where they are at, but I too have a similar concern. Will continue to watch them. in the mean time what a flying machine
