MOPED ARMY

if this is a stock bike, stick to the dex3/mercon. motor oils have detergents in them to break down and isolate carbon residue from blow-by, the cork in the clutches and the glue is very similar to the hydrocarbons the detergents eat, so it could cause breakdown. most people who need the extra slip dont expect their clutches to last more than a few hundred miles anyhow.
