Thank you, Ed. I took an hour and a half solo ride yesterday, it was above 90 and a bit humid. The back of my shirt was soaked. Why, you ask? Because, Spyder!
But also because it was the first time since last summer's rebuild that I drove it that hot out and that aggressively. Temperatures stayed right where they should, 180-185 on the oil. Fan came on infrequently, like it's supposed to. I was trying to get it hot to see what the limits are, if any.
Once it got really warm, I had to richen two cylinders and lean the other two and boost the idle speed a couple hundred rpm. Purring along at 900-950 hot idle now.
I'll say it passed the test. Soon, I'll be installing 4 CHT displays to go with the K-type thermocouples that are already on the engine.
Teby and I drive Saturday. My fan comes on at 190 degrees and it only came on a couple times and for not very long. Outside temps were nearing mid to high 80’s by the time we got done. The 2110 Pat Downs built for me runs exactly as it should. Glad to hear you got out.
