Sledge
I have the standard set up, no variable speed. Just an electric fan, the upgraded Rad from BDR, Meziere pump & sending unit mounted in the hard line. No issues so far, 3000 miles. I also put a Cool Carb plate under the carb, the ability to cool the engine way down at shut down is big for me because we do a lot of stop and go in the summer at the shore and I used to have a lot of issues with the fuel boiling out of the carb...no more.
Brent Lykins who built my motor said the same thing about coolant/
oil temps. He like the
oil hot to get moisture out and isn't concerned at all with 200 deg.
