On the Aprilia Pegaso 600 (air cooled) - 1993, where is the sprag clutch located? The reason I ask I was cranking it over on the electric start excessively, forgetting I had taken the spark plug cap off, now when I crank it over it makes a horrible noise and sounds like the starter is spinning, it starts OK on the kick start and runs ok, I was told it could be the sprag clutch worn. Is there a engine diagram or adobe reader file of the 600 on the net? Any idea of the cost to replace and availability of the parts? regards Wayne
