Bill,
I sure agree with Matt on this subject. I would investigate other causes
for the high CHT before cutting up the cowling. I would cut the cowling
only if all CHTs were too high.
His ideas are good ones and you also might try swapping the #1 and #3 CHT
probes. Maybe #1 is reading high.
It is very odd that #1 cylinder would be your hot one. Did you add an air
dam in front of it? If so, have you tried different size dams? Or
removing the air dam?

that cylinder? Try swapping the injectors between the hottest and coolest
cylinder
and see what impact this has on the CHT.

Stan, I tested the CHT probes and they are correct. I have the standard Va
n's baffle wind dam in front of # 1 Cylinder. I trimmed about 5/8th inch of
f the top and noted a small drop in CHT tempt, but it did not even out with
the other three jugs. I'll just not worry about it until after I get the w
heel pants and leggings all installed. Thanks for the help, Bill
