Did some redneck engineering on my cooler today, since I don't have the money for a bypass valve
It's still flippin' cold here and my oil wouldn't go over 75 C yesterday (170 F) on a ride with no highway miles, and it took ages to get to that temperature.
Your cooler works too well Mark
Made the shield out of a dvd case, fastened with simple rubberized twisties. I can untie them by hand and stick the shield in my toolbag should it be needed.
Works like a charm !
