From Diego: Some customers protest because a recent fragility of the exaust springs. Springs are not changed since long time, size, weight or charge are not changed. The typical use, that is different for every customer, for some reasons may cause a resonance and there are repeated broken springs on the same machine. When you replace a sping please put a small amount of silicone between the spring and the exaust, this "bridge" will cancel the vibration. Every kind of silicone may be used, all silicones are well resistant to temperature. We are considering to do this from the beginning, unfortunatelly the look is really ugly. |
