Entry 1 for today: Put pan of oil from draining the cooler into bottles. Reinstalled the seat. Hung the new oil cooler. Have to file the slotted holes a little for the AN4 bolts to clear. Bought 2 qts of the straight mineral oil. Still need to tighten the fasteners, hook up the hoses, add the oil and change the filter. While here, I'll torque the heads and plugs. At home, made up a 3/16" driver by cutting off about 1" from a cheapo allen wrench set and taped that into a 3/16" socket. Now need to find the 3/8 to 1/4 drive adapter so I can use it with the 3/8" speed handle to remove & install the valve covers.
