Stage6 PHBG Main Jet 40 (Aprilia, JOG, Zuma 50)
Description: Stage6 PHBG Main Jet 40 for Aprilia, JOG, Zuma 50, and many other 50cc base engines, and other PHBG Carburetors. Pilot jets for 19 and 21mm carburetor from Dellorto (type PHBG). In some cases, the pilot jets may be too small or too big, which you can see from the scooter's throttle response. If you start the engine but only manage to ride about 10m at walking speed, then the pilot jet is too small. If the engine splutters up to about 1/4 of the throttle, the pilot jet is too big.
NOTE: M5 main jets are generally used in 19mm carbs or bigger.
