Sorry, this might be a dumb question: I'm working on my swingarm/linkage bearings this weekend on my 06 yz450f. Some are in good shape, am replacing a few (got All Bals kit). Question: When I put the outer rubber grease seals in, what is the orientation? There is basically a channel on one side and the other is flat (and has the part number). They are currently installed in both orientations depending where on the bike (maybe from previous owner). I was thinking it was 'channel in', but if I look at this video, right around minute 6, it looks like he is putting them in 'channel out'.
