Aux tank and other stuff

I ordered my DX early last year, received it just before winter, and the accessories that I ordered with it did not show up till winter. Given that they sat all winter, and I just got them on last weekend.

Off-road pkg
rally pkg
heated grips
utility bar
center stand (still has not arrived)

I got the aux tank, for one because sometimes you need range, second the price would only go up for this option, and it is highly unlikely there would be an aftermarket solution.

Well, I got all the accessories on and a few things I've learned. Taking the main tank off is not a huge deal and you have to do it to do 90% of things on/to the bike. I suggest leaving the fairings in place if you don't need to remove them for access. The bottom fairing bolt's rubber bushing really needs to be two pieces, next time I have them off they will be cut in two. And, the main point of the post, is the fact the rear tank is extremely easy to remove/install. We are talking 7 bolts in all, with all being easy access. Six 10mm bolts hold on the tank and you have to remove the exhaust hanger bracket as well.

To remove the aux tank, remove the seven bolts, cap off the two fuel lines and secure (or remove) the wiring. Then reinstall the correct exhaust hanger (you have two now). Maybe 30 minutes worth of work.

My plan is to only have the aux tank on when going on long journeys. I'm going to run a little while to see if the new lines grow on me but as of now I much prefer the clean rear look. I've ordered the prerun moto rear rack (which can be used with the tank) and Adventure Spec side racks, signed up for notification when they start to offer them, so I'll have two different configurations for the bike, side racks for my Mosko moto reckless systems (for a slim look) and the aux tank, which also works with the reckless system. She really looks like a hefty girl with the tank and bags on 'er.

I'll be happy to answer any questions about the install. Not a lot of info out there on the aux tank and real-world usage.

Welcome to the forum @Toymaster! Great to have another owner on the forum! Do you have any photos you can share of your bike with the aux tank installed? Have you installed all the other accessories you ordered?

Two for one shot. Decat is going on tomorrow.

Got the decat pipe installed. Cat weighs over 10lbs. Makes more of a difference than I thought, figured with the weight being low there would be little difference. Picking the bike up via the kickstand and pivoting it you can certainly tell it lost weight.

I'm also decatting after my 1st service, have the pipe ready to go. Are you running the stock muffler? I will be at least to start. Sounds pretty good. Any plans for a tune?

Got a few items mounted this weekend. Added H&B handguards over the factory off-road handguards. I got the factory ones in the package, ordered the H&B last week instead of going with bark busters or acerbis due to liking looks. Don't know if this is my final form but seems that it may work out. Due to the stiff cast part of the factory handguards the attachment to the lever can be avoided. May install a screw from the backside of the plastic windguard into the H&B handguard or one could drill a couple of holes and install a ducati zip tie.

Also installed the AS3 chain guard and fin. The factory plastic one may be able to deflect a blade of grass. Maybe someone will come out with a chain guide that just bolts up.

@Toymaster Your AS3 chain guard, what model or part number is it? It isn't showing one for the DDX on the web site.

Seems the price went up slightly, probably currency fluctuations.

Last weekend I got the accessories activated: heated grips, aux tank, aux lights. On the way into work this morning got to transfer fuel from the aux to main tank for the first time. Went smooth, no spraying of fuel nor burst of flames while going down the road, all good things.

The low fuel indication came on around ~50 miles of range left. The gray "fuel transfer" changed state allowing the transfer to be selected, the transfer took ~5 minutes or so. Boosted the range by ~80 miles to the 130ish mile mark.

There is no way to manually override the system, one has to wait till the main tank is in "low fuel" condition to start a transfer. I totally understand why Ducati did this, they have to give a wide safety margin so no over-filling nor spillage occurs. In addition, the fuel is pumped into the cross over line at the bottom of the tank. If they tried to transfer fuel into the tank with more fuel in it head pressure could be a factor. On the other hand, if the transfer fails for some reason one could be stuck in the middle of nowhere with fuel in the wrong place. I have aux tanks on other vehicles, all self-installed, and I transfer fuel to keep the main tank topped off, this way if something happens to the aux system you have plenty of time to get fuel. This technique is not really possible with the desert X aux tank.

Carrying a piece of hose suitable for fuel usage is not a bad idea on any long-distance journey; never know when you may need to deal with fuel. A siphon may not work because of the elevations of the two tanks, may need a primer bulb. At least if you had this you could manually transfer the fuel from the rear into the main tank.

Do you have to stop to transfer the fuel? Or can you do it while riding?
@GonzaloF You do not have to stop to transfer fuel.

Also, the aux tank fuel pump is on the left side, so you can also transfer while on the side stand.

Got the perun rack mounted. No trimming required, just did the offset.

Mounted some aux lights this weekend. Baja Designs

Used the factory brackets, rubber isolators, and screws. Had the aux lights option activated and then used that signal to turn on the relay that came with the Baja Designs lights. The BD lights have a higher amp draw than the OEM fog lights. Oh, and the screw holding on the light bracket is temporary, will buy one better suited soon.

The factory brackets, rubber bushings, and screws were ~$130 and the lights ~$240. Still less than the OEM option and I got more lumens.

Here is the location of the factory aux light connector. It can be accessed without removing the cowl. The connector has three wires, the switched +12 is the middle one, the other two are -12 and a constant +12.

The circled parts are the ones I bought for a clean install. The bracket and rubber bushing were cheap, the screws were not.

Got the new center stand on. I have to say it is as light as you can go with steel and it do the job. A few weeks ago I put an aluminum center stand on my T7 and the two weigh about the same. I have a decat pipe and, of course, the stand is made to go on a bike with a cat, so the only thing I would change is it being tucked a little more, since I can.

The other thing is on the right side, had to replace the pivot bolt with a shorter one. My decat pipe is closer to the stand/foot peg mount than the factory cat, so the bolt hit the exhaust pipe. Went 10mm shorter, 12mm x 1.75 x 40mm and a slim nut is what one needs to buy. That side has the spring on it so it needs more than the other side; they have a flange nut supplied to back up the bolt so the pressure is not just on the threads, more surface area for the force to be distributed upon.

Thanks for the write up! Which decat do you have? Also how solid does it feel?

It is a thick pipe, and short, and fixed on three ends....so very solid. Got no complaints on the part quality at all.

Oh that is the Shift Tech de cat. I will let you know if it’s the same with the Termi de cat. Installing later tonight.
