Filler cap holding water...

[Sunny Jim]

This has been going on for some time now - each time it rains or when I wash the 'bike (1150 Adventure) a bit of water holds in the innner lip of the filler cap - don't look too pretty either! (Have read a thread about this being blocked and poking it with strimmer cable - tried that and can't seem to get around some of the bends ).

Have opened the hole with a small drill bit, had the tank off and can blow back up the tube leading to the hole and all seems clear - it's as if the large rubber washer on the underside of the flip-up part of the cap is smothering the outlet hole...

The manual shows the whole unit as the 'roll over valve' with 2 x pipes connecting it with BM clips - valve is about £50 and don't have the specialist tool for the clips so would be looking for something else.

Before I commit to spending and sorting it does anyone know what any other solution may be pse?

Drain Hole - Gently poke some thin strimmer cord down there, emphasis on the gently

Thanks John - been trying that and can only get it so far (oooerrrr Mrs!) - as above, had the tank off and can blow back through the pipe without a problem???

You Squirt...

...some WD40 down it first using the red nozzle adapter that it comes with. That's what I did to help loosen the grime and rust; I gave it a few squirts, watched it dribble through and drip out of the hose end and rodded it with some wire extracted from 3 core electrical cable. I then gave it another good squirt of WD40 to ensure it was flowing well and somewhat protected.

The thread I suspect you read convinced me to subscribe as a way of repayment for the knowledge base.

pipe clear

I've had this problem on my '02 1150 & the folks who spot welded the steel part of the breather pipe around the inside of the cap had too many amps on & collapsed the wall thickness of the pipe into the bore. I had to drill through from the open end, through the weld & then silver solder the hole over to, in effect, build up the pipe wall thickness again.Then it works again.Can't see anyone at all admitting they made a mistake with the amps, but that's what it is, of course, IMHO !

 

[Sunny Jim]

Thanks everyone - tried the WD40 with no gain. Not very good with the soldering Rixter but I think it's certainly going to be a blockage that ain't going to shift. Oh well, looks like a new unit.

i had to put thin 'steel wire' on the end of a drill and slowly worked mine clear but it took a while . the turning effect slowly dislodged the rust and cleared it......it was a battle tho

Have used a piece of old cycle brake cable wire. Unravel the end a tiny bit. Put in a drill a put the wire down the hole.

Works well to clear any rust etc

Have you checked the other end of the hoses ? if they are swapped around it wont drain. Just a thought.

 

[Sunny Jim]

Stripped the unit out today and, as Rixter suggests, the blockage seems to be where some welding has been done - no way will it clear. New unit fitted within half an hour without any problem at all. Thanks again for the advice everyone.

Mines been doing this as well

Can you poke WD40 etc without taking the filler assembly out of the tank?

Apparently so but been trying that method for too long so opted for removing it altogether, trying to clear it (getting nowhere) and so went for a new unit. Not difficult to do - you only have 1 x pipe to remove and that's obvious when it's out of the tank - the bit marked '1' you see in the picture is easily seperated from the problem bit.

The unit is £33 plus VAT and a petrol pipe clamp available at Halfords.

On a scale of difficulty I would say 3/10 - just make sure you cover your tank and the hole.

Thanks for that, I managed to blow mine clear using a Cycle track pump connected to the overflow pipe.

 

[Sunny Jim]

Well done - still poking away at mine for the shear hell of it and getting nowhere!

Washed the bike, then left it on the side stand over night. Next day went to refuel and as I opened the filler cap, big pool of water runs into tank! Feck! So tried strimmer cord but no go so tried wire in a drill plus WD40 and success! So cheers for the tip!

Norris - you might want to go to Halfords and get a bottle of stuff that you put in the tank to dry up the water - costs about £5 and lives on the shelves along with fuel additive - sorry, can't remember it's name.

I rode it for about 30 miles afterwards expecting trouble but nothing happened but that might be cos the tank is still pretty full. However, I will get some additive cos I know water went in there! Cheers again.

 

[Sunny Jim]

That's the stuff John
