Water not draining from fuel filler cap.

[Throttled]

Today's government permitted time outside and exercising was washing a very dirty bike. I found that that water is not draining from around the filler cap. I poked a twig as far as I dare down the little hole, that did not work. Any suggestions as to how to clear whatever is blocking the water from draining, thanks.

compressed air, some squirty degreaser like brake cleaner or chain cleaner

I can vouch for the compressed air route

Thanks. I have some air in a can for cleaning computers and it comes with a WD40 type straw that would be ideal to squirt down the hole. I will try that.

There will be a drain hose coming from underneath the tank . It's probably got twisted , melted on the engine or shitted up in some way . That's where I'd be looking .

Suck the other end of the tube.

Way I used to fix this on my GS was to stuff some paper towels into the petrol fill.. and then blow up the tube. That always cleared it and the paper towels would stop (whatever it was) getting inside the tank.

another way is to straighten a metal coat hanger, (not that you see many of these nowadays) and poke that down the hole

If you must go the invasive route don't use the coat hanger.

I speak with experience having dealt with Mazda MX5 drain holes (Google it lol).

There is a thing called a trombone cleaner available on Ebay for about a fiver.

It is a flexible plastic coated wire with what I can only describe as an emaciated hamster on the tail end.

Absolutely brilliant for clearing drainage holes.

Please check first as some have non return flaps in them so direction can be important.

Cheers
