I just did my first flight on my RV8 about 30 day ago. All went well ( usual small Items). I am at 19 hrs and was hoping the CHT's would come down . They are fine in cruse 24 square or even 25 square 360 's. but 1,3 and sometimes 2 go over 400 to 415 on the first climb even at very shallow high speeds. I check timing, I checked baffle leaks, I tried the washer trick. As the temps get warmer here in northern Ohio, My fear is the CHT's will still be a problem.
So I bit the bullet and did the " baffle mod behind number three, and cut down the dams in front of 1 and 2.
When the winds stop blowing at 35 to 40 and the rain quits I will report the results.
