  • gas tank help

    ok here goes guys i was out working on the bike this weekend making sure it would start and run since i aint got a garage and it has been cold and snowing out but the bike is under a cover, but my problem is the cover was not on for a week and it snowed and my gas tank lid had water in it and when i opened it to see how much fuel was in it there was water in there too so i think the fuel got water in it but i got some stuff put in it and some seafoam to clean the carbs and the fuel sytem and the engine out and i put some 94 octane in the tank and this summer when i get it out i am going to go put some 104 octane in it, but my main question is is there anyway to keep water or over spilled fuel from pilling up under the gas tank lid

    the bike is under a cover now and it ran great so i am just waiting tell spring time now to ride

    There should be a drain from under the fuel lid (in the recessed area) that is a tube that goes inside the tank and out the nipple at the back of the tank (under the seat).
    Could be this drain tube is clogged.

        did you get all the water out?

        if water out, add stabilizer to gas
        run engine for short time to get stabilizer in to carbs

        or park in living room

          Bandet01,
          If you pull the seat, you will see a tube on the back of the tank. This is the drain from around the fill cap, and drains the water to the bottom of the bike. I have a bike that was parked for 10 years, and the drain is still working. Unless you have a LOT of rust around the tank, your drain should still be working.
          An easy check is take some warm water( because it's cold up there) and pour it slowly over the gas cap. You should see the water come out on the bottom of the bike, about at the center stand.

            If seat off

            why not just blow through other end of hose to see if clear?

            btw
            is your tranny fixable with the grinding etc. I read in other posts?

                  mro;
                  My trans may be repairable, but it's getting BAD. I've ordered a trans from Andreas, and three gears from Yamaha. I think my project bike also has a bad transmission, so I want spare parts. I plan on putting in the parts starting on the 30th of December. I will be checking gears, and doing any needed grinding.
