R1150GS fuel tank
I recall reading on one of the GS lists somewhere that I can improve the speed of filling my R1150GS (standard) fuel tank by drilling a few vent holes in the top of the tube that sits in the filler neck.
I am sure however that BMW put the tube there for a purpose (other than to delay filling and reduce capacity that is) and I assume that it is some sort of restrictor to prevent over-filling and thus ensure that the fuel has room to expand without pouring out of the breather as the temperature rises.
Does anyone have any thoughts?
