The Piaggio Ciao may only run without an air filter and exhaust because these components can restrict the flow of air and exhaust gases, which can affect the engine's performance. Running without an air filter allows for more air to enter the engine, which can increase power output. Similarly, running without an exhaust can allow for a freer flow of exhaust gases, which can also improve performance. However, it's important to note that running without these components can also lead to increased engine wear and environmental pollution. **

To achieve a speed of 85 km/h using only a sports exhaust, several modifications can be made to the vehicle. Firstly, the exhaust system can be upgraded to a high-performance sports exhaust that allows for better airflow and reduces back pressure, thus improving engine efficiency. Additionally, tuning the engine to optimize performance and installing a high-flow air filter can also help increase power output. Lastly, ensuring the vehicle is well-maintained and in good condition will contribute to achieving the desired speed of 85 km/h with the help of a sports exhaust. **

The Yamaha DT 50R running at half speed and emitting white smoke from the exhaust could be due to a few reasons. One possibility is that there is a problem with the fuel mixture, such as too much oil in the fuel causing incomplete combustion.
