I don't believe that is so: the oxy sensor & ECU will maintain a stoichiometric condition (on a 990 obviously) with a smaller pipe. Engine power would decrease with this, though.

My understanding is that you gain a little in the low end and lose a little in the top end. But, with the power avaiable with the 990 does it really matter? I'd give up a hp or two for the decrease in weight.

FI is in close loop operation at a relatively small part of its envelop (small steady throttle). At all other times it is based on intake sensor readings.

I wouldn't think you can use another model slip on with the KTM as I think the pipe end/diameter is specific for that bike. You might be able to use like a superduke can? Not sure about that one.

For those who have the ADV tank - New Bracket is Sweet!

I worked with a fellow ADV inmate who is a phenomenal welder. He has solved the issue of the weak ADV bracket that gives and bends allowing your wheel and swingarm to hit the ADV tank. The nice thing here is it is a bolt on or off application - so you can remove it if ever needed. 750 miles so far - 600 in the dirty all over Death Valley, Sedona, and Flagstaff. My rear wheel has bout 1/2 inch of space when fully compressed so it does not rub the tank.

R&D


Ensure the fitting is accurate


before installation


Add the tank


Finished product




utilizes the two original bolt holes on the tank


Avoids this..


and this:



If anyone is interested I can put you in touch with the developer. He is in NorCal.

Cheers,

Nice mod Is that the KTM OEM pannier mount? I just ordered a Touratech stainless steel mount and the front brace that runs to the foot peg is interfering with the tank.

I think that I own the KTM version of these racks but someone may be able to validate. This is what I have:

http://www.ktmtwins.com/ktm-950-990-...carrier-system

When my Gobi side cases are on this setup they do touch the tank so I have attached a piece of thin no-rub to the area. It's very minor but I did it just to be safe.

I don't have any experience with any other racks as this was made custom for me, which I assume will work for anyone whom has the KTM racks. I know 4 other guys who have the same tank installed and they are looking to get this bracket. It essentially eliminates ANY movement of the tank. Of course the original ADV tank design was meant to work without the racks but 98% of riders I know have racks. Take photos and show us, maybe we can help.

The problem is in the way the front support of the rack attaches from the foot peg to the bag support/mounting oval. On the Touratech mount that support piece is straight. The KTM mount has a bend in it. Touratech USA is willing to ship me a KTM mount to use as a pattern if I want to modify their mount. So, I need to decide if I want to ADVTank enough to make the modification or just remove it and put it up for sale.

The correct response would have been "Works for me."

It's a tough call because there are several different ways you could do it depending on what luggage system you have (including none). When I look at the "stock" bracket, I think taking a lot of it off would be beneficial too.

I did a 2-1 change to my bike during long winter. Here are the raw results, Leo Vince midpipes and silencers were taken off and polish made 2-1 pipe + single Wings silencer was installed. I didn't change fuel mappings, both dyno runs had exactly the same software inside the ECU. Only other hardware change was new OEM air filter because I managed to create an extra hole to old filter when it was off the bike... Old filter wasn't in bad shape, I could have used it for this summer most likely. Also engine oil and coolant were changed but I doubt they have much effect. :)

Dynograph for Leo Vinces:

Interesting results, but they can only mean one thing, that your AFR was more suitable to the 2-1.

I believe he mentioned a Wings or Akrapovic Silencer.

That's a big difference especially because the later was at a hotter time.....
