    I have had problems when my bike hits the reserve and you change over the tap intermittently it would not rev correctly as if it was starving for fuel. I had it back to the mechanics and have had the fuel pump and ignition box replaced.
    On the weekend ride it played up again when I hit reserve changed the tap over and it played up and could not get full revs and was lucky to get to 90Km/h.

    I had a look at the carby and it appears that there was water in the fuel.

    My problem now is what to do I have drained the tank, cleaned the carby, pump & fuel tap.

    The only filters are in the tank should I put a inline filter in the fuel line to help prevent this again.

    Is there any thing else I can do to get rid of the water?

    Thanks for any advise.

    I would put in an inline filter anyway.

    The thing I would want to know is how the water got into the tank.

    When u drained the tank did u completely dry it out inside?...like with a hair dryer?

    It is sitting in the shed empty at the moment drained it well and blown it out with air. waiting to hear what else to do before refilling it.

    PD186 this won't help taking out the water off the bike but I have a question: is the gas station reliable? Here we have several complaints of fuel mixed with water or God knows what else (solvents and other stuff), not specifically where I live (south) but near big cities like São Paulo it happens more frequently.


    Do you always refuel at the same gas station?


    And by the way, gasoline is hydrophilic. If you left it in the open it will retain the humidity. Also, I'm not sure how a inline filter would help, it only retain impurities as far as I know.


    Hope I didn't miss the subject completely...

    I normally fill up at the local fuel station and never had any problems with them. Last weekend I had a club ride and I was running late to get to where we meet so I filled up at a different station and as the bike had been running well since it was at the mechanics untill now. I am also thinking the fuel there may be contamanitated. As I think the couple of times I have filled up there and had problems soon after. I just need to be more orginised and get my fuel the day before.

    would hate to dry the tank with a hair dryer as the fumes could spark an explosion. the old treatment for water in the tank was half a cup of metho which absorbed the water.had similar trouble this year with the car. think i fixed but still have to clean the injectors,drained fuel and it had brown dust? through it and was not rust. e10 crap probably in unleaded tank.

    Water has fumes that can explode?  :icon_scratch:

    If I were drying a tank with a hair dryer it would be because I had drained the fuel ,removed all petcocks and caps and washed it out several times with hot soapy water and hosed it out with the hose on full.....and then get it dry quickly and completely to prevent surface rust forming.

    one cut the bottom off a jerry can and after a week of leaving in the sun and washing out  went to weld a new bottom on. went woosh and flew across the yard when welding started. only can think of fumes in the metal as there was no smell. fuel and sparks are plain dangerous and i value my life and want to live to 108 and die in bed with a beautiful woman killing me with love!!!!!not kaboom from a hairdryer.lol.

    I though that a hair dryer was not such a good idea but was too polite to say so  ;) .
    I will let it dry till the weekend and put it back together. May put some metho in as well. can't hurt  :Thumbs_up:

    Ive used a hair dryer on 3 tanks and I survived......its a common practice
    Its not as if its inside the tank.

    And comparing a hair dryer to a welder is just piddle .....a thousand times more heat,power, sparks and gases produced which is probably what nearly blew u up.

    friend, petrol fumes are unreliable. no smell and off they go. the hair dryer is an electric motor and element. you might get away with it a hundred times then the tank could open up in your face. once bitten always careful.
