Dellorto main jet holder size 208 suitable for the original Aprilia RS50, RS4, RX, SX, Derbi GPR, Senda R, SM and Gilera RCR, SMT carburettors with D50B0 engine.
If throttles and performance restrictions are removed, the fuel-air mixture must be corrected. A basic measure is to replace the nozzle assembly in the original carburetor with this larger Dellorto nozzle assembly. Depending on the extent of dethrottling or additional performance increase, the mainjet must also be adjusted.
