There were all sorts of anecdotal stories about synthetics and the havoc they wreaked on clutches in the Virago forum I belonged to. Mobil1 also made a lot of statements and disclaimers regarding the reason for the different type of oil for air cooled engines/bikes, and how the additives they had in the V series oil were critical to proper clutch operation.
I used to buy it by the case (six bottles) from a place in Miami that sold all sorts of unusual lubricants. They would have it on special twice a year for $50/case shipped. Last time I looked at it here at a FLAPS it was over $10/quart.
