After 5,000 kms the drive belt exploded in powder... Wise me, I had one under my seat so i change it, but when i opened the case to change it, the front part from the base of the engine fell down on the floor and tere is 6 little busings like tubes to put back, but i never had time to see how. I have been looking all over the net to find the right schematic, but even Benelli does not have the roper information on their website if they ever have one. So if you know how to put all that back in, contact me, i love that machine... when it works...
