    You haven't been tempted by Powercell's new tank?

    Sure. But back to running a rear tank and the factory tank. I get five gallons out of that.

    I did this also on my 990 (and I was also at this year's Rally but didn't make it over to CJ's camp). On the way to the Rally (I came from northern California) I found that my stock-sprung KTM 990 will bottom out on an acorn if it's left in the road. Off road, I just got used to that thump/clank sound when I hit some edge with my front end. Even on the rides at the Rally (sans camping gear and not with full tanks) I can easily bottom out the springs. So my advice is (if you haven't already) PLAN TO RESPRING YOUR FRONT END WITH THE SAFARI TANKS. You may also need to do the same for the rear - for the camping gear.

    If you haven't re-sprung your bike, you may want to consider this first before going back to the 2 into 2. Might save you some bucks because you'll need to do it anyway.

    The only other problem with the Safari tanks is that if your riding buddies don't have them you either will have to go solo or not enjoy them. I opted for the solo on this last trip home - I had some ground to cover and didn't want to hang around near the gas stations all day. :wink:

    Hey Spencer,

    You might try moving your fork legs up a cm or so if they're even with the top of the upper triple; it's free...watch that you don't smash the top of your fender into the front fairing at max travel, tho (or the tire into the fender if you're high....:evil...fender, that is...).

    So I've made up my mind?... Going to go back to 2-2 exhaust & safari tanks. Pry going to look to sell or trade the 2-1 wings and aux tank set up as a package

    Wont give you the range of the Safari dromedaries, but I have found this a very neat and well balanced solution mate. About the same capacity of the side rear tank but IMO much more securely mounted and the weight is central and low.

    About the only downside is you need to remove the seat to refuel but I have my luggage configured so I can do this in less than 5 mins, and as I always run a std seat after 350 kms my ass thanks me for the few mins extra break at fuel stops :lol3

    Think ill just go with the safari tanks not looking for a hidden tank looking more for max fuel storage weight distribution and max engine performance

    I'm running a 2-1 with a Wings Muffler. I seem to have lost a bit on the top end, but picked up a tad in the midrange. Had it on a Dyno after installing the PCV and the 2-1 with the Wings. Topped out at 103 HP at the rear wheel.

    Is the Wing muffler a bit more restrictive than the Remus or Akrapovics?

    I don't think so: without the baffles they're pretty much the same diameter. And I really don't think it would matter that much given that the main bottleneck is the 2-into-1 header.


    Oh, and Mmmmmmm purdy! :D

    Tank is still wrapped up, I'll get to it tomorrow. Thanks spencergt66 and thanks ADVrider for making this possible! :clap

    It's an addiction the Pharmacy can't give ointment for :rofl

    You would pay thousands more to get that extra 1 hp between pretty much all the aftermarket mufflers and as Lupin 3rd quite rightly points out the perf tube is pretty much the same throughout.

    To get any great advantage the system needs to be balanced for air intake, fuel mapping, pipes and muffler.

    More important to a V2 is equal length headers to get correct purge and pulse, not getting that right will lose HP and torque.

    Also with a V2 having the balance/connector pipe closer to the exhaust port will increase torque/lesson HP, further away will increase HP but lose torque so it is a balance between them.

    This.

    Look at Gregor's thread for a case in point: all his work was being wasted by not having the intake well setup. Once he got the right bellmouths, HP and torque jumped up.

    Velocity stack length and profile can make huge differences on sprint cars,, cant believe it would be any different on the ADV....

    You can compensate for uneven pipes with stepped headers..
