Tankscrew .. ?

[FURBAR]

Hier,

Pics are bad .. but after you open the fuel cap there is a place where a screw seems to be missing, don't know what it is or whether it's supposed to be a hole with an open thread, it's the hole on the right of the pics within the tank but not in the tank ..

Anyone shed any light on this .... proberly simple answer, which i don't know .. surprise surprise ..

A lot of tank caps have "dummy" screws in them - my Yamaha has a couple, could be one of those missing.

mmm . don't think it is a hole, unless it has a v small opening, and or gauge ...

Is it the overflow for when you fill the bike up too much, the extra goes into the hole, down a pipe inside your tank and into the rubber pipe hanging off the underside of the tank, all the way down to the underside of the engine.

Well that's what my bike does anyway. If I try to get as much fuel in as possible a little ends up on the floor via the overflow pipe.

it also drains any water that collects so it doesn't end up in the tank

Yes, it may well be that, it's the thread within the hole that made me think somethings amiss ...
