I am under a foot of snow right now......as soon as I can go for a ride I will let you know. One thing that I have found, the coolers seem to only add about 300ml more oil. I measured the volume of the filter housing and the cooler and came up with 275ml and added 25ml for the amount carried in the lines. With 1.3 liters the oil level in the case seems to stay good after warming the bike up. I am not sure why the instructions say that it adds 6-800ml. I will keep this updated as I sort out the oil level situation.
