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
