    Hi All, You have probably notice from my previous posts that I want more fuel capacity for my f8gs with out having to spend $2000 aussie dollars on an unpainted touratch tank which I then have to butcher my stock tank to mount up. So this morning I had a call with IMS about a front fuel tank for the F8GS. They are keen to do a small volume run similar to what they did with the aprilia rvx/svx
    http://www.apriliaforum.com/forums/showthread.php?t=182361

    To get the tank at a similar price (approx $750 + $40 USD) to the aprilia tank and a lot cheaper then the touratech we will need to be a least ten ordered.

    To get the ball rolling we need an advrider who lives in southern California to lend their bike to IMS for them to check and confirm they can build the front tank within budget and if so create the moulds off it. The moulding /design /prototyping could take up to 6 weeks. Given this is such a big ask for someone to give their pride and joy up for a couple of weeks everyone on the initial run to contribute $40 USD towards to donor bike owner's tank. Which means if your bike is the donor you'll only have to pay approx $350 USD.

    So far I'm keen to get one of the first, now I need 10 more interested F8gs owners one who must live in or be able to drop off their f8gs to IMS in southern California.

    Please PM me if interested and I'll update this post with names, please note if this goes ahead there will be 50% payment up front to IMS with the remainder paid on completion of your tank.

    Thanks,
    Chad.

    I would be interested, and I can only imagine others would be as well providing it's a good solution. I know it's premature, but do you have an idea of how this would differ from the TT tank in regards to the butchering of the stock tank? Did they have an initial idea of volume?

    One of the request I made was not to cut or chop any of the stock parts and the whole kit should be reversable. The f8gs tank has 3 holes in the top, the fuel pump, fill and breather. My suggestion is to replace the breather system with a plate and two inlets, one for fuel in one for return air/fuel. A pump system will be needed similar to the aprilia tank. Requested capacity is at least 16litres doubling our current range.

    Sounds like f650gs could be an option only concern is mating the front plastics, if the replacement tank runs forward to the duck bill then no issues. I'll drop by my local deal and have a good look at he air intakes but from memory under the skin the f8gs and f650gs are the same. :D

    Chadams,
    I'd be interested but I'm in Colorado and my boss says "NFW am I letting your sorry a*# leave to SOCAL just so that you can get a custom fitted gas tank - WTF were you thinking????!"............so, that leaves me wanting in on a newly fitted front tank but no time to get out there. :waysad

    Whoever donates, take 'em something with crash guards on it. Would be nice to be able to fit the tank with bars already mounted.

    I'm interested in theory, but obviously can't lend the bike.

    I'd actually be happier with an XChallenge-type auxilliary tank that is mounted where you suggest, but isn't actually plumbed into the main one. That's where all the complexity is. Just fit it with a transfer pipe with a simple tap and gravity feed, I'll transfer the contents manually. It works for my Cessna.

    I take it the tank design is going to completely cover the airbox/battery compartment? This is one big disadvantage of the touratech tank as well if you plan on riding in the desert and dust (which is probably where you want the fuel range in the first place!). Perhaps some sort of quick release on the hoses to make removal easier if you are going down this route? Ideally it would be nice to retain the centre panel and have two side tanks bolt on. There could be complications with crash bars though you could argue you wouldnt need them if the new tank protects the radiator.

    Is it possible to have a replacement tank for the current underseat tank designed? There has to be capacity there to make a bigger one. For starters ditch the plastics on the top and use that space, then extend it out the bottom and rear towards the tail light a bit more square (a little like how the front of the safari tank for the Super Enduro is). Only complications would be how any pannier racks would fit with this design. Something like the Holans and touratechs should work, Jesses wouldnt and anything that attaches via a bar to the holes underneath the subframe wouldnt (metal mule, BMW vario, happy trails) unless there was a gap left in the middle to allow the bars to pass under. Heres a crude pic of what I mean:

    Personally I would rather go this way, with the option to retaining the oem filler cap transferring it to the new tank. A rear tank will help keep the weight down low rather than up high near the battery box. It would also eliminate any F650GS vs F800GS issues that may arise from adding a tank to the front. Food for thought?

    I just loaned my bike to Scotts for two weeks. I'm semi-close to IMS.
    I may give them a call and see what they have in mind.

    :pimp
    My bike is slowly becoming a whore.

    A thirsty whore. Since the change to the 15T counter sprocket mileage is down to around 40.:(:

    +1, and it doesn't even need to be gravity feed if the main tank isn't vented. Turn the vent hose from the main tank into the pickup from the [vented] aux tank and let the pressure differential do the rest. Physics works. No electrics, less cost, probably more units sold.

    I'm interested if it doesn't look like the XC Aqualine (TT) monstrosity and the color matching is close. 15L +/- is a good size.

    Hi the objective here is to get 11 people who are willing to pay 50% up front for a quality built front tank from IMS, there has been a lot of discussion about rear tanks, peg packers, bum tanks, roto packs, jerry cans..... etc... This thread is for f8gs & f650gs owners who want a large front tank with out the price tag of the touratech, the 50 million parts and the butchery of the stock tank.

    Actually I don't think it's such a problem up front. If you're expecting to do such travel you most likely will have gear with you that is loaded to the rear of the bike and as such providing a counter balance in case the tank is full.

    The problem I see with the design on the back is that it will limit you quickly with side cases, etc. Unless you want to make the rear of the bike stick out a lot (which I would hate in case you travel in CA cities).
