Lost Performance Today????

[1 FAST VE]

I did not have a chance to test with the new pump, so today was the first ride. It pulled hard to 72.3 (8100)and rpm's fell to 7800.
I got back and found I over filled the oil 10 to 12 oz. and the cooling was down 16 oz.
Could the two togather cause this you think???
Why did the rpm's fall after an hour of riding, low coolant????
Thanks!!
BTW Oil is fixed and Water/Wetter was added.

David, i didn't see you out there today. Be sure to show up at my camp for the cookout tomorrow. Looking forward to meeting you.

YES! overfilling the oil could cause the performance loss as well as this unbearable heat wave we are having
