Second day I had it the Duc didn't start at all, back to the dealer. They tried everything for two weeks. What they told me was that a faulty cable to the left front indicator caused the problem. Then at 4500 km at a tour it didn't rev higher than 2000 rp/m. Back to the dealer. Mechanic says it might be the electronic accelerator handle, will see when I get it back in a week or so.
