anyone know the depth of the bgm/keihin pwk30

im using a mikuni at the moment but its about 10mm too deep with a filter on so im wondering if the keihin is a tadd shallower?

According to the Scooter Center catalogue the bgm pwk connecting stub is 70mm from the base. Mikuni TM24 is 60, TM30 is 70, and TMX35 is 85.

I've just measured a bgm 30mm and the overall width, bell mouth to the end of the inlet stub is 83mm, hope that helps.

are you checking the dimensions for clearance issues here a large bodied 30mm (can be bored out to 36mm )

thanks guys, im using a jimmers manifold with a tmx30 mikuni (which is so much nicer than the 35mm) but im trying to use the breath sweet cam lam filter. it goes on but is tight against the series 1 panel. if i glue some felt to the rubber where it touches the panel to stop it wearing then it should be fine but i was hoping that the keihin was the same depth as the tmx35 which fits fine with a filter.

the mikuni tmx30 is 88mm so 5mm saving is good but im not sure i want to swap just yet when there is the option of a modified manifold.

ive got alternative filters too so ill try them on the dyno on wednesday.
