This makes for superior fuel atomization and also maintains the proper fuel curve by position of the venturi in the throat of the carb and not the outer venturi. Because of the problems associated with outer venturi designs, this system enables a true high, low, and mid range circuits. The BRM carb also features a low circuit improvement with dramatically increased acceleration. All kits come complete with linkage arms, throttle and oil ejection brackets, billet throttle wheel, fuel rail and are pre-jetted. All other models use an easily removable solid mount carb which also has the parallel shaft configuration.
All models use the same carbs, only fuel rail lengths and linkage rods vary.
BRM carbs use Mikuni high and low jets, fuel filters, diaphragm and pop off springs. BRM carbs require auxiliary fuel pump and come with primer fittings. BRM carbs are the lightest fuel system available and tune the same as SBN carbs. Air filter adapters are built in and use all clamp on style air filters. Throat design features an annular discharge inter venturi, to make for superior fuel atomization and proper fuel curve, 45mm, 47mm and 50mm sizes are available.
