Hello.  A friend of mine has spent the last while debugging his KR Special.
 He's pushing 170+ with a 65 hp Rotax 582.  One of the biggest problems he
had was jetting at high speed.  With time in the cockpit he finally
discovered his problem and it was something which I think we could benefit
from.

In a nutshell, everytime the thermostat opened on his engine, the resulting
hot air flowing out of his rad entered his engine air intake and created a
rough running engine.

Keep this in mind when designing air flow through the cowl.
