i have a stock grubee 48cc engine with a dellorto carb. i got the carb jetted where the spark plug is the perfect color. it damn thing would always 4 stroke at high rpm. i finally bought a boost bottle and honestly there was no power increase but it stopped ALL the 4 stroking. my question is, would an extended intake by its self be better then a boost bottle? im afraid if i remove the boost bottle and go with an extended intake, the 4 stroking at high rpm will come back. on a side note, with a boost bottle, as you ride the little tube going from the boost bottle to the intake fills up with gas and when you let off the throttle, all that gas in the tube gets sucked up and the engine runs extremely rich for a few seconds.
