Malossi MHR Team carburettor kit. MHR (Malossi Hyper Racing) team stands for high end racing for the Malossi Team racing scooters. The 21mm PHGB Dellorto carb is the ideal base for mid to high-end cylinder. Hand-operated choke and racing air filter included. The PWK, TM or VHST 26mm or 28mm carbs offer even greater power, but require more fine tuning. You are never far wrong with a 21mm. Dellorto M5 main jets supplied.
