    Hi,

    So to get this straight,

    You merge the left TT and the right TT tank fuel lines into one hose then run that hose into the stock tank's vent hole located at the back right corner of the the stock tank?

    Then you run the TT tank vent line(underneath the TT tank) up and around the instruement cluster and attach it to the right side, kinda high up to minimize water/dust contaminating your fuel. thus allowing both TT tank and the stock tank to equalize the pressure in both tanks.

    So there is NO drilling the stock tank.
    Petcock stays open ALL the time.
    Both tanks vent using a shared vent hose coming out of the TT tank.

    BRAVO!!:clap:D
    In theory, it sounds like it would work! And you stated you've done this using a jerry can for many miles.
    As long as you have an airtight tank, the fuel pump should provide the fuel suction to draw all the fuel to the engine.
    Sounds like you have to have the "canisterectomy" done too (US bikes only).


    Sounds awesome!
    In about a month, I'm gonna try this and will report back with pics!

    Until then.

    Ciao,

    Espi

    Well kinda

    If you run the lines though the vent, you only get about 2.5gal of fuel, the rest stays in the bottom of the tank. I have a full write up on my build thread. I have a fuel pump to move the other 2.5gal.

    I was talking to my dealer today and they said they got an e-mail from BMW NA that there will be an F800 Adventure GS and that it will have an 6.3 gallon tank - stock, and the pricing will be released shortly. I assume it will be a 2014 bike coming this fall. So screw Tourtech, I will take BMW stock any day. Dave

    see the new sticky thread

    Also the I don't think Touratech had a tank for the 2013 model. I have the TT tank - and yes - I think the new BMW Adv solution is less trouble.

    Friend of me did this on his F800GS and this works perfect! Bought the TT tank myself some months ago, installed it the same way and it works splendid (after having some minor problems in the beginning).

    You don't need a fuel pump to get the other 2.5 gal ...

    THATS what I wanted to hear!!!:clap:clap:clap

    So there is enough suction from the main tank to transfer the fuel uphill from the remaining 2.5 gallons of fuel from the TT tank to the stock tank!

    Yaahoo!!

    much appreciated,

    What sort of "minor issues" did you have?
    Did you install a fuel filter? if so, where?
    Did you take out any valves in the fuel line?

    thanks,:ear

    I removed the stock tank's vent line and replaced it with a fuel line (6mm) that goes around the dash and then back down to the tt tank.

    But it still didn't seem to work so ...

    Eventually contacted this friend and found out I had to make a little bend downwards from the T-fitting (where the 2 fuel lines from the petcocks come together) and then back up to the dash etc ...

    And finally it worked!

    Didn't install a fuel filter and the valve in the stock tank's vent line got removed by installing the new, longer fuel line.

    Good Morning Sohere,

    Thank You SOOO much for sharing with me your recipe on making this TT fuel tank work without drilling. I should be doing this in about a month and will post up my step by step procedure with pics.:clap


    My Best,

    Pablo

    Has anyone modified their engine crashbars to work with the TT tank, if so pics please...

    PS: I order a tank this week but was warned today by local TT rep it could take up to 5 weeks to arrive ex Germany... Hopefully I see it sooner :D

    Been watching this thread for a while hoping someone came up with a crash bar solution. I was just about to drop my bike off at a custom fab place for bars when I saw the post.

    Can you send along some more photos?

    Thanks!

    super easy... just cut the left to right brace and flip it backwards to allow the bar to run across and down instead of up and across... Some spacers in the middle and you're done

    Have they held up well?

    Good looking welds. What kind of welding machine did you use? What diameter are they? I'm thinking of doing an outer sleeve to double up over the re-welded section.

    Thanks again for the great heads up on using the Givi Bars. It's making my winter desert riding season more exciting already.

    So, does the Touratech tank go onto a GSA model? Anyone tried it?




    No reason. Just thinkin out loud.
