[QUOTE="Fred W, post: 1321981, member: 3828"] Exactly. So there is still no logical path for oil to reach the clutch plate friction surfaces. And yet, they seem to work for thousands of miles once they are properly cleaned and whetted with engine oil. I think maybe it is much ado about nothing. The friction surfaces work as intended with or without a steady stream of lubricant. So long as they are not [I]stuck together[/I] for some odd reason, such as a long period of time unused or perhaps assembly paste getting things gummed up, the lack of oil flow is not an issue. We know that dry clutches are prevalent in automotive applications (whee manually shifted transmissions still survive) and they seem to work just fine also. Why do we think that these motorcycle clutches need a steady supply of oil to make them not stick? Apparently, the Yamaha design engineers are past that little bit of confusion and do not worry the clutch plate lubrication will be insufficient. Whatever the hypothesis, they do work, and they work quite well. For lots and lots of miles. [/QUOTE]
