Ok, here we go again.. Anyway. I just was at the InterBike Bicycle show where Magura had a booth set up. Of course they had Jeremy McGrath's CRF450 there outfitted with a magura clutch. Very sweet. Anyway. I was talking to the guys about it and they said, for the Smoothest, easiest pull, to use Finish Line 2.5 wt Fork oil. They said you need to change it more because it seems to get contaminated more easily than their Mineral oil but other than that it's great. They didn't recommend the ATF because they thought it was actually too thick and created a harder pull. This is Magura's words not mine.
