    Geez, Bigem. With all that weight up high and that far back, it's got to affect your handling, doesn't it? Scares me just to look at it. :yikes

    That configuration would most like not survive a trip to Tierra del Fuego.

    The stuff in the tail bag was all very very light, so it was not a problem at all.

    The heavy stuff was in the panniers and the Kolpin was low enough not to give a top-heavy effect.

    That was the load I took on our desert run in September last year.

    The bike was nothing short of brilliant across the dunes/soft sand and made the trip so easy compared to the 1150/1200s on the trip.


    I will probably not use this setup again as I think larger panniers and less stuff on the rack is the way to go in the future.


    This is my prefferred luggage setup, with the Kolpin in place from now on.

    Well, my previous bike was an R1150GS. I got tired of having to worry about my next gas stop after 150 miles. I heard about a slightly dented Adventure tank that could be had cheap. Bought it for $100 plus another $15 to ship it. The tank was silver, bike was yellow. Painting meant body work and worrying about scratches so I went bedliner.

    Linky

    Fast forward a few years and big crash later and I want another bike. The F800 GS looks like it will fit the, erm, "bill" apart from the relatively short range (200-ish miles). So when I buy the bike I buy a TT tank through the dealer and prepay installation. 4 hours. They took a bit of a bath on that, IIRC the total time was closer to 12.

    So here it is. Same bedliner, for similar reasons, plus there isn't a good crashbar set that I know of that would protect a painted TT tank.

    That tank setup looks great! I like the functionality of the Rhino Liner Finish. I am ordering this same unpainted kit next month, but was looking at the more conventional satin black finish.

    Did you go with heavier front springs for this extra weight?

    Was any special primer used in the application of the Rhino Liner?

    I can't see the kit's fuel line disconnects in the photo. Where were they installed?

    Do you have any close up photos of the finished tank?

    Thanks,

    I'll try to get some more pics of the tank this week. What specific bits are you curious about? Disconnects were installed. May need to install the springs, but so far it seems quite rideable. No primer, but I regret that choice. I worry that the first drop will start the de-adhesion process.

    One major issue: At about 40 mph a whistle starts. I've got all the likely candidates taped up with gaffer's tape this afternoon and will check the results tomorrow.

    Cheers! :slurp

    I will be interested in your findings about the whistle. More photos appreciated.

    One question... since the TT tank is higher than the stock tank and the TT tank is connected to the stock tank, how do you fill it? Do you fill the stock tank all the way to the top, close the cap and then fill the TT? I have visions of gas seeping out of the stock filler once the TT is filled! What am I missing?

    There are valves at the bottom of the lobes on the TT tank. I've only filled it once with those valves closed. Got to reserve and then opened them. Next fill I'm planning to leave them open to see what happens, but yes, I would guess that it would overfill the main tank.

    I thinking that filling only from the TT tank would be painfully slow as the fuel ran through the small lines to the main tank or you'd have to fill the main first. Once the whole system is full can you open the valves on the TT or will the fuel leak out the tank vent via the charcoal cannister? It would make the most sense to use up the TT fuel first as that weight up high make more difference to handling than the under-seat fuel.

    Touratech clearly states in their instructions when using the tank to turn the petcocks off until the main tank is in reserve as indicated by the flashing low fuel warning. I would have concerns about overflowing the main tank and flooding the vapor canister if you have the petcocks open with a full main tank and full TT tank. My procedure will be to turn off the petcocks when filling up both tanks and turn them on only after going to reserve (main tank). I will leave them on until refueling again. Leaving them on even overnight shouldn't be a problem if they were only turned on after the main tank went to reserve. At that point both tanks should equalize level without threatening to overfill the main.

    One extra I am working on is an inline solenoid fuel cutoff valve so I could control the fuel transfer while riding. Saves having to stop when reaching reserve on the main tank. All you have to do is throw a switch. Wire that to switched power and the fuel transfer line automatically closes when turning off the engine. This is an extra safety factor when fueling or parking.

    Looking forward to extending the "bandwidth" of this bike:D

    Seems right to me. I'll have to find the instructions you're referring to. :D If you are serious about the solenoid let me know. (I'm assuming it would switch off when you switch off the ignition, not when turning off the kill switch, yes?)

    You know I really love this idea, and was starting to seriously consider it, but just got a little discouraged after reading the last few posts. I guess I just assumed that you would drain the TT tank as you rode from the start, therefore lightening it up sooner rather than later. Still the best solution all around sans the cost, but not quite what I had ultimately envisioned. $1300-$2k is a big ticket item.

    Yes, the solenoid fuel valve would be powered (open) only when the key is on and the fuel switch is turned on. This way any setting of the petcocks and the fuel switch the fuel flow will be blocked with the key off. If I can fit this in the space available the petcocks could be left open until tank removal for servicing is required.

    The instructions I am referring to are the installation instructions that can be downloaded from Touratech's fuel tank description. The way I see the relative positions of the bike's under seat tank and the TT tank you don't want the fuel lines open when filling both tanks.

    Perhaps after you have some miles on the tank you can offer a review on what is working and anything that we can improve. I will be ordering next month and depending on order status I should get the project completed a couple weeks later. In addition to the tank I will be changing springs and redoing my accessory wiring harness so I don't have any fuses or junction boxes under the new tank. It will be fun:D

    I was going to ask about the porosity. Let us know how it goes. :lurk

    What's the venting on the tt tank, and why not just route the stock tank vent to the tt tank?

    I don't have the tank yet, but from the instructions it appears the TT Tank vent is led to a tee with the main tank and then routed to the canister. There is a one way check valve also involved that is between the tanks but I can't figure it out exactly. It will likely make more sense when I do the install. The main thing is you don't want the main tank overfilled. Surplus fuel will go to the canister or to the ground if there is no cannister.
