    Can I come and steal one as well...one of the steel ones, that is. :evil

    On the actual design of the subframe, I saw an article somewhere where the standard frame was re-inforced with huge success. The engineer that did it had a whole technical document on forces at play, that drove out the final design. If I recall correctly, the issue is not the strength of the subframe, but the way the lower attachement location is not balanced, giving rise to tortional forces. I'll try and find it.

    12 Gallon = 45 litres.
    I had to carry 55 litres, and having some of the fuel at the back is the way to go. I carried the 30+ litres at the back, with the standard frame, and had no issue.

    I have my toolbox upfront and low (on the skidplate) Tools, weight per volume is a lot more than fluid, so you can balance the bike front to back easily, without having huge volume in the front that gets in the way once the riding gets technical, imho.

    Keep us posted on the frame though, I would be very interested in the final design and design considerations.

    yes its steel ....hahaha ..um yes we have talked about the mount issue ....keeping the stock shape i think we have come up with a solution ....

    we dont tecnical stuff ... more wide open around here ... sand tracks ....it dont take long to go threw 30 ltrs ....with the tank bra and bladders on the side of the tank its well balanced ...gear at the back ...water onboard at the rear ..keeps the weight even

    theres a few pics and talk on the aussie subforum xr650r owners
    about the steel subs

    My stock carb and 4.3 had me around 200-220 KM I think.

    My 6.3 with TM-40 I can almost always do 400KM, often a lot more. I bet if I had to on a gravel or paved road I could do over 500KM. I've never pushed it though. I've done low 400KM a few times.

    There has only been once I've hit reserve at 380KM, and that was in Baja, all deep sand roads and roosting around corners.

    I get around 50-52 MPG with the TM-40 and 70lbs of gear.

    For those wondering, 1.6KM / Mile.

    If you ride WTF out there, having a tank with lots of gas is a GREAT feeling. I've been in some VERY remote places and knowing my tank is half full still always brings comfort.

    Haha.

    I can't say I share the same way of thought... I had less stuff with living off my bike for 4 months... Provided I didn't have to bring food or cooking gear.

    I think we covered this before, but always fun to bring it up again. ahha.

    In my opinion, lighter = better. Not only easier to ride, more simple, quicker pack-ups, etc.

    I know you aussies like your massive sleeping mats / tents, but you should really see about a Thermorest or similar pad. If you don't need thermal properties, there are ones that weigh very, very little. The ProLite + which is my other matt weighs quite a bit more but much, much warmer. What I brought on my trip was awesome for size, but too cold. Even here in the summer I feel chill using it, often resorting to my Pro-lite Plus for better sleeps.

    its hard to xplain .....the swag on the back has my clothes and all sleeping stuff

    its now been retired off the bike ...am going to tent from now on ..i have a exped mat was in my swag

    on that trip we had way diffent temps over the 14 days from freezeing cold to hot

    the bladders sit up front there a must ..we have big distance with low fuel options

    the bags on the side 1 held food and 1 held spares and nick knacks ..all up the gear is light just the swag makes it look heavy

    running the CSR this yr for 4 weeks ......gear is getting cut down as its all tuff sand .....bladders will still be there but going a giantloop tent and exped and sleeping bag ....4 xrr's in the desert makes it easy for us to spread the tools and spares between bikes ...

    gunna take 1 set of clothes and throw them away each week and buy new stuff where i can

    60 ltrs fuel on board and 10 ltrs of water ...hard going in desert

    What kind of reserve range are you seeing with the 6.3?

    No idea. I haven't tested it but you actually have two reserves provided you have the plumbing run appropriately. The 6.3 has two petcocks on either lobe. The second tube has to run either above or below the carb. In either event you don't get all the gas because the lobes go below the carb intake. In a REALLY bad situation you could then tip the bike over and fill a bladder / bottle then tie that into the carb to use all the gas. Once again, not great but it would get you that extra 10K if need be.

    I need to fill up from empty and see what the tank actually holds, then see how much is there when I fill to better guage my distance. With possibly 500+ KM of range I don't worry too much about gas and know 400 is no issue unless I'm working the bike really hard, and even then I only hit the reserve once on my way to San Ignacio in Baja. I had to pull over just before the military stop to turn on my reserve.

    not to beat a dead horse, but here's my oil level after oil / filter change and 1.7 QTS oil added. Idled bike for 5 min and shut it off and checked the level upright.

    [​IMG]

    and here's hontri's level - I haven't added any extra to see how much it takes to bring it up to that level. Anybody just adding 2 QTS at the oil change?

    Yoh Piney Those black marks on the steel oil tube are the correct upper full mark and lower add mark in relation to the dipstick. I have never let it get down to the add mark.There is not much oil in these things to start with. My bike takes 2 quarts to fill after a complete oil change. I start by adding about 13/4 quarts, warm up real well and then add oil slowly till i reach the upper full mark. Those marks are right in relation to the dip stick.:D

    another 1/2 qt will prolly bring mine up to your level - I'll pop the Scott's off tomorrow and see what it takes to bring it up. Appreciate your advice.

    It must be a blast riding there.
