Ignition timing can have a huge effect on temps.
Get a shroud...a metal one...see pic of melted JBG shroud after sustained 230 degree temps. THEY TOOK CARE OF IT NO QUESTIONS ASKED...I was running hard.
Most guys, correct me if I'm wrong, run close to 200F.
Flex fans do wear out over time.
Electric fans are a bitch to mount unless you do hood latch mods etc. but most say it was worth it.
Ducting/sealing/routing airflow pays off big time if you are a slow speed wheeler in hotter climates.
If all else fails, run an oil cooler with fan or move to a cooler climate.
Best of luck,
J.D.
