Recommended is the Malossi or Polini air filter mat. by means of one of our nozzle sets is an easy way to guarantee both performance and reliability. In case of further modifications, especially on the cylinder head, exhaust as well as on the choice of the exhaust, a simultaneous adjustment of the carburettor e.g. The basic spark plug fits very well for an unmachined 172cc Malossi cylinder with original exhaust.
