For a powerful two-stroke engine the fuel-air mixture ideally needs to be fed into the engine with as little obstruction as possible. The inlet tract should be short and without restrictions. This exactly is where the BFA inlet manifold excels. Short inlet tract Plenty area for carburettors up to 40mm. Perfectly flowed with a stuffer The inlet tract of the SIP-BFA crankcase is perfectly designed for the unhindered passage of air-fuel mixture into the engine. The reed sits well centred above the crankshaft and its angled towards the piston crown. The carburettor directly bolts to the reed. Layout BFA inlet manifold The BFA inlet manifold was designed for these engines, hence it is a perfect fit. It’s cast in aluminium with an integrated stuffer. The reed itself is a modified Kart-Racing. Gaskets and bolts are included valve with 4 huge carbon fibre petals. The carburettor itself is fitted with a connecting rubber. This rubber is not included but needs to be selected to fit the chosen carburettor. The inside diameter of the manifold is 40mm, the outside diameter where the connecting rubber sits is 45mm Conclusion: The best possible way for the fresh charge to enter the SIP-BFA crankcase. The best setup - our SIP-TIP:Only fits the SIP BFA crankcases from 187cc to 306.The go to carburettors for a powerful setup are either a Dell`ORTO 39 VHSB 39 ND (art.-no.
