ADV tank installation on F650GS / F800GS for extended range

It is doable, it won't be pretty.. so I didn't do it. I did rig it up and it looked goofy and it limits the rider's space to being confined to the front half of the seat.

That's too bad. Thanks for the update.

Do we know what top boxes will fit on the ADV tank bracket?
Even a smaller box than the Givi 55 would be uselful.

GB thanks for starting this thread. I’ve been eyeballing the ADVTank for a while now but was waiting to see if anyone with Jesse Bags would install......................guess that’d be me:


Jesse bag mounts run over the top of the rear mounting bolts.





This creates a problem with the standard kit provided by AdvTank. Basically everything needs to be jacked up 30mm. So with Threads All M8 x 1.25 (found at local machine shop), I removed the threaded studs and added new ones that were 30mm longer.


From left to right:

Front posts: 1) old stud 80mm, 2) old stud in barrel 141mm, 3) new stud 109mm, 4) new stud in barrel 167mm (86mm of thread showing)

Rear posts: 1) old stud 38mm, 2) old stud in barrel 118mm, 3) new stud 69mm, 4) new stud in barrel 143mm (45mm of thread showing)



Fortunately, AdvTank provides a number of spacers. The pic below shows 1 x 26mm. In my final configuration I used 3 spacers (not pictured) of different lengths (26mm+12mm+6mm) on each front post.



Because the tank is 30mm elevated on the Jesse bag mounting point, I wanted to brace the forward edge of the tank since it is now basically on stilts.

I trimmed a spare motor mount down to 30mm and then used a router to cut a groove down the center so that it sits flush on the back deck.











I did have to run a tap through the front barrels because the bolts would not fit flush against the top plate. Everything else runs per the instructions.










EDIT: Topped the main tank and then filled the AdvTank with 1.6 gallons on the side stand and rode 93 miles. At that point the main tank took 0.45 gallons but the AdvTank would only hold 1.5 gallons (again on the side stand). Guess where the rest went?

Fortunately The gas cooled the hot muffler and did not combust.....

So, I think we'll call this good.

Well that's cool. Any pics with the Jesses on?

Si claro













The red bottle is .24 gal. It's my traveling "moron bottle", as in note to self: "you are a moron for passing that last station."

The Rotopax are pre-advtank and are normally carried empty until I think I want to push and possibly miss gas.

The nice thing about the AdvTank is that it drains first so the weight disappears early. I will probably keep the Rotopax just because.



EDIT: Oh yeah! Rode Cody, Wy to Durango, Co. 703 miles. Last leg was 353 miles. I ran some 75mph interstate, mostly 65mph state roads, and screamed through Red Mountain Pass (Ouray, Co). Got 53mpg.

Went 299 to empty and topped off with the Rotopax. Went 350 miles to the gas station and put in 6.6 gallons.
My capacity is 7.8 meaning I still had 1.2 in the tank. At 53 mpg I have a 400 mile range!

First day of use was great!

But Day 2 has me perplexed. I think pressure in main tank is preventing flow from AdvTank.

I'm now in New Mexico. It's 100°.

I stop to fuel with 9 miles to empty. Open the main tank, pay at the pump, pump only 1.2 gal and she starts to overflow. I pull the pump and slam the lid. Checked the Advtank and I can see gas. I had the main tank open for several seconds (perhaps longer) before I pumped. I suspect that once opened the AdvTank started to drain in.

I pulled the seat and looked at the hoses don't think they were pinched. The main tank was under positive pressure when I opened it to pump fuel.


Read through THIS THREAD but still am unable to answer the following:
Where is the purge valve? Why is the main tank not venting? Heat?




EDIT; So re-read the thread and believe I need a new vent valve with check ball. Or just run a line from the Advtank to ground.


EDIT EDIT (kind of like PPS): In the end, I simply removed the check valve all together. Even with a new check valve I was having pressurization issues. Once I removed it no problems. I ran thousands of miles with it this way. I was completely happy at that point.

Hi Guys,

Anyone out there running the Adventure Tank with the Giant Loop Great Basin Bag.
I am really keen to see how far forward the bag sits on the bike.

I am really hoping to get rid of my Hard Panniers and change to this setup.

By the way I am getting around 500 klm range with the Adventure tank now. Great Product.

Cheers

If so, any modifications necessary?

That's a pretty cool tank, too bad they don't make one for the R1200GS!

It should bolt on without mods.

Yes we are. I thought I replied to that email, but it must have been another one.

You did. Timing on getting your reply was after the first email and
and a later Adv Rider inquiry.

For anyone looking for a new in the box tank at a substantial discount,
see my flea market ad here.

Nice looking setup. Wish it had a locking cap though.
