Chris,
I have data from Thundehrill back in Oct. Nov. time frame. Let me take a look at what our pressures were doing that weekend. We are running 10/60 oil, the air temp that weekend was in the mid 70's. We were running 2:06's counterclockwise with the crows nest on Hoosier's.
I know our water temp is rarely over 205. If the oil had been doing something out the of ordinary, I'd remember it
