    Acerbis.

    Factory flush mounts are really complicated in terms of moulding/venting compared to standard Acerbis-type cap.

    I'd say flush mount if the venting doesn't complicate things.....on the other hand it sort of takes away from the "replica" look......tough call. If it were me I'd stay true to the replica.

    Hay Pete Ive just made this tank for my 640 Adv and I used a flush mounted cap from a boat shop and there only about $12 each and for the vent I just turned up a nipple and weldered it on.

    Thanks Matt - ive been to a couple o chandleries but couldnt find exactly what im after. The screw caps have it - small as per the main on the 640A - can get the acerbis units as per OEM - but now looking for a source for the filler bung if anyone has any contacts. Prefer stainless over ally if possible.
    No petcocks - banjo bolts leading to dry break connectors which will "T" before a fuel tap isolating both rears from the fronts. Will intersect the balance tube between the 2 fronts with a small filter inline.
    Now back to the shed.

    Bring it on.....

    I'll support a local manufacturer everytime...

    I know i'll probably pay more but thats the price for old mate's shed hours/r&d,(at least I get good old Aussie quality tried and tested for this enviroment.)

    I've got a 950, and i'm a potential customer....

    Thanks OZ - I guarantee they wont cost more than the Africa Queens tanks and will fit and be a more authentic replica.
    Back to work......

    Not atm - I had a couple of late orders for the Aust safari and my CF bash plate mould has taken priority because I dont have one that covers my GPR low header. I expect I'll have something in 2-3 weeks tankwise.

    Hi Pete,

    These look like they are going to be great!

    How much volume do you think each will be?

    Any chance you'll be building them so that only the left one can be used?

    Will these work with hard bag racks?

    Thanks - not much to look at atm, but they'll be butterfly pretty shortly.
    Ive been speaking to a couple of friend laminate/design engineers recently and have come to the decision to make the 2 tanks into one that'll utilise the under seat storage space. Mounting will require removing the top subframe mounts and pivoting it down to slip the tank unit into place - custom under seat/rear taillight set up required. As my main design requirement was max capacity (= range) this will give me approx 6 lt of extra capacity without any drawbacks. There will still be under seat storage, but not as much - and abs is out. As it will be one unit it'll only need one filler (rhs which is higher when on the sidestand) and one petcock/dry break/fuel tap. All told it'll hold approx 22lt if my mathing is goodest??? :deal Once Ive got it fitted and trialled It'll be moulded and possibly offered to the greater good if there is enough interest. If its a dog then I'll go back to the original 2 tank idea - but I cant see that happening any time soon. (unless someone has mucho $$$$$):wink:

    Are you saying it is less expensive to build two tanks, or one large one? I'd think there may be more appeal for the two tanks as some folks may only want one if they are running a single exhaust.

    My thoughts are two tanks would offer more flexibility to convert back to running bags, etc when max fuel capacity is not needed.

    My .02, but I am interested in the project and possible purchase either way.

    Sorry - I may not have explained it correctly. In its first incarnation Im after a tank that will carry the most fuel and that it seems is a one piece that incorporates the under seat storage area. Once ive got it done and if there is enough interest id consider making twins for those with the single high exhausts. But 1st its the single max range unit.
    Deadly - seat/tail light unit is a 2nd piece and will have limited storage capacity (think O2 cylinders, small levers, tool bag, etc).

    But the bash plate must be done 1st. and there was even a sacraficial plate used over the OEM's that was a disposable unit after each day - how cool.

    Sounds perfect, look forward to seeing pics of a mockup or prototype. Good luck.

    Hey Pete I love these 'build it yourself projects' as you get alot of satisfaction from the end result.

    However these rallye tanks dont make sense to me. (unless you're entering a rally) If you need alot of fuel you obviously plan to ride along way, if you ride along way you will need alot of gear which will also be mounted on the back. All this weight on the back makes the bike difficult to ride in tricky situations and all but rules out sand due to the lightness of the front end.

    I am also looking for an answer to carrying more fuel after a recent 9000km trip to the Territory from the east coast. I carried enough fuel on the back at times to do over 650km but narly creek crossings and soft sand were a real challenge. I am keen to do a Simpson desert crossing unsupported but there is no way I could do it with all the fuel behind me.

    IMHO the only option is the Safari tanks to transfer enough weight forward to allow the weight distribution with camping gear to be somewhere near neutral. I am also concerned about Safari tanks but there seems to be no alternative.
