The reason why we upgraded the exhaust + tune..is because of an engine vibration problem (in hot weather i.e. Qld) Local BMW seemed unable to rectify. The Motorcycle after exhaust + tuning is a complete different bike to ride (more torque, enjoyable, less fuel/using less throttle opening). All good. Before these mods. it would struggle at 175 kmh now it will easily go up to 200 kmh. Used our motor racing knowledge for the design of the headers. Endeavouring to upload photos.. (learning).
