Air intake hose in the BGM PRO range, suitable for Lambretta series 3 - Li, LIS, SX, TV and DL / GP and late series 2 air box elbows to fit the Mikuni TM24, Dell'orto / Standard Lambretta carburettors - 200cc Scootopia SH2/22, 125 / 150cc SH1/20 and Jetex carburettor bellmouths. Can be used as standard through the airbox or can be used to run a remote air filter in the top. 
 
A big advantage of the BGM PRO intake hose is the lower outlet. Here the Spitback from the carburettor is not collectef in the hose so the idle system cannot clog.
 
As you can see from the bottom picture, they do fit the Scootopia SH 2/22 carbs but they're very tight to get on, and needed to be levered on before fitting. There's no way this can be fitted with the Carburettor on the manifold!
 
Diameter Ø - 45mm (Mikuni TM24, Dellorto / Scootopia / Jetex SH 2/22 Etc).
