PostSubject: Blocked tank water drain   Tue Sep 18, 2018 11:35 am

Was about to post a question and then resolved it (good enough for now anyway). Bike has been deluged with rain and spray for three days and I noticed tank drain was blocked. Tried running wire from top but it always gets stuck before it gets to any blockage (only know that cos it still won't run all the way thru.); Tried vacuum pull and tried blowing it out ....no joy

Lifted the tank and tried reaming out obvious blockage - hard 'salt like' deposit from the water drain outlet. After about 1/2 hr careful twiddling drill bits I managed to get drill in water drain depth to same point as it goes in tank vent (tank vent isn't blocked) before it hits something solid. Tried wire and blowing out again and no joy......without knowing internals didn't want to drill deeper in case I hit fuel.

.....but seemed like the blockage stuff is salt type deposit; and it seemed to dissolve in lemon juice (or at least absorbed it). So I put plastic pipe onto drain exit and filled it with lemon juice and left it for an hour (pipe hanging up).......Then (with rag still stuffed in tank filler hole (Thank God !); just a slight blow cleared it out and sprayed lemon juice everywhere ....ran more lemon juice through from top and now seems OK.

Only questions I still have is whether the water drain nozzle at bottom left-hand side of bike is easy to remove ? Tried ginger tweak with 13 mm spanner but bottled out a full yank to avoid ripping something out that shouldn't be out...and anyone know what the internals look like between the drain hole and the outlet ?

Cheers
Paul

I am so glad you have the problem Paul, as i do as well, and perhaps an easy solution will appear, that doesn't require fruit!

It's probably not salt but limescale unless you have especially salty rain in the UK. Limescale dissolves in acid like lemon juice, but you could also have used cleaning vinegar which is what I used when I had the same problem.
I also cleaned the nipple and used a metal wire in two directions, so from the drain down and from the nipple up. I didn't remove the nipple as like you I had no idea how its fixed and how the internals look. So far the drain has been working well again for at least 6 months or so.

I had this problem and it re-occurs, I drilled the hole out to make it bigger, first removed from tank, second time drilled in situ but bigger hole again.
The drain pipe passes through the tank and has a couple of sharp bends so running through a brake cable doesn't always work.

Antarctica is the driest continent. I don't know much about the motorcycle community there, though...

strangely, there is some evidence...

"...had taken a 350 cc Velocette to Mawson in 1960 and expected that other motorcycle enthusiasts had since done the same. What he didn’t expect was the number – some 35 bikes between 1960 and 1980. One was a 500 cc single cylinder Matchless, which stood out because of its long life, from 1968 to 1977."
