Hi Tom
The tank I fitted was for Dr Steve Breuning, he will surely add a post here soon to tell us how the tank perform on longer trips.

and generally think it's the business...

not sure what else to say but the tank works a treat might even put a African Queen under seat tank on as well.

I've done the install myself and pictures can be found on the UKGSer* ::::* For BMW GS Enthusiasts site if you search for me. I'm sure you'll find it.

I also swapped the shocks and added progressive springs and now the bike is

With 15L each side, plus OEM Tank = 43L.....
ALMOST my perfect bike; not quite there yet

Nice one Ozi, I got the AQ tanks for mine. They are in Singapore at the moment, I'll be riding down from Bangkok next week to get em fitted, will post a few pix in a few weeks.... Safe riding cobber!

Thanks Muzz.
Could you please do me a favour and take a picture of the parts that come with your tanks ?
I think that mine were missing some parts, in particular, possibly an alloy bush/sleeve for the front (ie lower-front) mounting position of the tanks.
Also - check for gaskets between the fuel fittings that bolt onto the tank; both upper and lower, plus the central tank mount that's semi-circular in shape.

My fittings have since begun to leak, and have now caused all sorts of issues, as the fuel leaks onto the cylinders (Yuk!)

So, I recommend that you get some gaskets custom-made to ensure that this doesn't occur.

I found that the quick-disconnects tended to leak sporadically so I went to fuel line "barbs", that aren't quick disconnectable, but they will NOT leak when used with suitable hose clamps.

Also, DO NOT fill the tanks to the brim; they will siphon from the upper nito the lower tank when the bike's on the side-stand
Another owner on Adventure Rider Motorcycle Forum also mentioned to me that this also occurred with his bike, and the AQ guys don't publish it as a known issue.

If you're not going to put the bike onto the sidestand for the first 10L or so, then you could arguably get away with this issue.

The issue with the tanks is that they're low-volume-hand-built (very well, I might add), and some detailed finishing work was short-cut I think to get them out into the market.

Once you have the tanks sorted, it makes riding the bike a little more demanding in slow going, but then the trade-off is that you're not worrying about fuel range.

With all the brackets, etc installed, it only takes about 15-30 minutes to install the tanks, so you don't have to have them on the bike if you're ionly doing short runs (around 180-220km; depending on your right wrist....)

I'm now looking for a nice "clean" saddle-bag mounting system for my HP2.

I'll be checking back to see how yours come up.

Cheers,
Dave

guys what is your experience with the AQ tank / HPN tank and cooling / overheating of the HP2.

I have the standard tank and my bike temp. go to Max when I hit traffic after a good run on the motorway (durring the summer).

The AQ tank appears to restrict airflow on the side mounted (under the side tank) oil cooler,

The HPN tank comes with a repositioned oil cooler..does that work better?

I have also seen a thread (on ADV rider) on fitting two oil coolers on the HP2 (the second oil cooler is from the Mega Moto.. ) anyone tried this?

could you share your experience on the impact of the fuel tanks on the cooling system.

thanks

As yet, I haven't experienced any cooling temperature issues using the AQ Tanks.
They do look like they close it all in, but in actual fact, the design of the tanks allows for wind to be directed into the tank/frame/engine cavity

Does anybody knows which manufacture does this gas tank for HP2 E please..!

G'day Felix,


I bought a HP2 Enduro in May 2012 (Absolutley love it !) After 10,000 K's in all terrain and reading up on as much as possible. I too have been looking at larger tanks as well as other bit's n pieces to get it a more ergonomic. I also like the look of the tank you posted and have spent hours searching the net as I imagine you have for the maker without luck.

George T's remark on overheating is a valid one, I also experienced high temp's in traffic on hot days (lost again) I think the HPN tank with the repositioned oil radiator (30% cooler or so they claim) is a damn good option albeit an expensive one.

I've come up with a list of mods I would like to do and I do understand these are personal choices.

HPN Tank & radiator.
Megamoto or sport gauges with taco.
Change the stock final drive ratio: From 2.82 to 2.91 possibly 3.0.
Full Arkrapovic exhaust system.
Ohlins or White power back n front.
Screen & heated grips.
Panniers & rack with rear frame support.

Then again (Yes I can just about hear some of your thoughts) it would be cheaper to buy a used GS and leave it stock standard !

Cheers Dave

hi HP2ers


in respect of the larger fuel tanks for the HP2 I had been looking around the options for a while and I think the HPN is the better option.

The touratech option (and I think the AQ is similar) is basically two side fuel tanks that link to the main one, great idea as you can potentially take them on and off depending on your requirements.

In practise people have told me that it is a bit fidly to use and there is always a leak in the system of fuel connectors (between the three tanks)

I have seen the HPN fuel tank is all HP2 conversions here in the UK and nobody seems to complain about it.

I haven't got a large fuel tank, simply because the trip I was thinking and planning never happened and I traveled all through eastern europe (and as far as turkey) with the stock fuel tank and a five litre plastic jerry in my tail pack (touratech soft tail pack for HP2) which I only had to use once or twice.

If I was going on a trip now I would consider the underseat tank conversion which is much cheaper than the HPN but it only gives additional 6 to 7 lit.


In terms of other changes on the HP2, I have the following:
Wilbers rear shock and front progressive springs,
Akrapovic exchaust and remus headers
Wunderlich screen
Unifilter - air and pre filter
Touratech tail rack, sump guard, oil cooler protectors,

I would like:
auxhilary spot light pref. an LED
led tail light and indicators
upgraded forks, either new cartridges (options from ohlins and marzochi) or new WP 48 or even Marzochi 45 gold, forks

or even change the HP2 for a twin 800cc to 1100+cc Dual purpose or offroader that is lighter than the HP2 (don't think it exists yet)

The tank pictured is made by Boano in Italy. It carries 7 US gallons of fuel, looks good, is flimsy fiberglass, takes some funky plumbing to unite the three chambers, was built for the Megamoto for use with an attached front fairing, is I believe no longer available, and is probably not the best use of your money. I have one that needs a little work if you simply won't be discouraged.

Two and a half years later, I wonder how many of us still travel their HP2s. ???

Still lots of dedicated HP2 riders. I can't imagine the day when I don't have one. What a bike!

Hi,
it's a long this post is sleeping.
I m the owner of an AFQ tank but without install diagram or photos it's very hard if someone can help me it will be great.
Thank you

Ozie if you have any pictures of your install?
