Hello I have just had a look at a nc 30 fuel tank parts diagram and noticed there doesn't seem to be a pipe listed for the fuel overflow vent around the filler neck ... the reason i'm asking this is because my bike has never had one of these fitted and it seems as if it should otherwise fuel is just going to run straight onto the top of the engine should it be splashed around the filler neck ? thanks in advance

Ah I see where it vents .... In the little cup on the l/h side of the top of the airbox

so doesnt have a pipe?

Nope, and it shouldn't. The only pipe for the overflow is at the bottom of the airbox, to route the fuel down the side and out the bottom.

ah.i got ya!
