Hello everyone!! I tell you I have a dune 1.6 SCl model 94, 1 year ago I made a change of hoops and metals, from there it started with the problem. Cold starts without drama, but hot gets heavy, repair the donkey, 1, 2, 3 times, I got tired and bought a new donkey ...... The same, I asked one of a friend who has a one and It worked fine ... and the same. I put an additional mass on the battery and the donkey and it remains the same. Any idea what it could be.......
