Jabiru engine
My 2011 J230SP LSA has 435 hours on it with no engine trouble. I almost always cruise at 2850-2900 rpm's.
The first thing my mechanic did when I bought the plane (new) was re-baffle the engine which resulted in an average reduction in CHT's of 65 degrees farenheit. The factory baffling is inferior which results in higher operating temperatures than are necessary.
If my choice was to correct the baffling and risk the factory's ire or live with the inferior factory baffling and replace the engine, I'd opt for the former.
And BTW, has anyone had the pleasure of an engine out in flight due to improper venting of the fuel tanks from the factory? I did, twice, and there's a simple fix to prevent it.
