Basically the black horn looking things that stick out of the carbs/injectors.

The RC8 Stack or "Trumpet" as KTM calls it is shorter than the 990 ADV ones.

Thinking is that the shorter stack should let it more air for higher HP#s.

The Longer 990 ADv ones result in more torque.

These will be here soon for testing.

BTW,
Air filters just showed up so I hope to start shipping out Fri and Sat.

The orginal stacks for the 990 motor (Adv,superduke,SM/T/R) are the same
The RC8 stacks with 2nd flies removed used in a airbox should give a gain starting from 6500rpm till limiter.
But it doesn't loose torque down below.

And the fun part is they cost allmost nothing, i paided 5 euro (6-7 US dollars).

example from a superduke:

The RC8 stacks fit the standard 990 throttle body soo the hole size in the base plate are the same.

I measured the distance between the middle of the 2 holes and it is 12,6 cm
So if the distance between the middle of the 2 throttle bodies from the RC8 are the same...
And if you have more then 4cm distance between the throttle body and the frame...then it could fit??.

No 950 filters yet. Two more weeks at least.

Has there been much discussion about socks for these filters? That'd be super convenient.

I was thinking of takng mine down to Home Depot (when I get it) and see if one of the foam filters for a shop vac would be the right size. That would make it kind of a twin air.

A 950 that doesn't run the fan in Summer traffic.Great idea. I suspect that the fork legs create vortexes that probably spill over the stock fairing. The notch only being three inches from the radiator. Speculation of course since you can't really tell what's going on unless your in a wind tunnel. I've done some aero testing with various teams I've worked for. Some even had a big enough budget to afford wind tunnel testing. I thought that would be fun but it is one boring day I tell you. Looks like you have more than doubled that distance plus widened it out a couple inches. Nice mod with good results.
Suppose I could data log the airbox pressure sensor. Do some pulls on the dyno with no fans for a base line setting, then go ride and see what I get.
Just tying up a loose end here.......
I took some photos of the cover that was being lifted off at speed. As the air that passes through the radiator it is isolated from the carbes I know that the shrouds that I made are not responsible for pushing air to the carbes so this is air traveling through the steering stem area putting pressure around the carbes. My answer to the popping cover was to bolt it down This is the cover on the seat side lifting and flexing its clip open. It takes some pressure to do that.

A lot.... we've been working on that. This project got huge before lots of little details could be worked out, but this will only get better.

Lots more info in Vendors.

Got my CPR Rottweiler through CJ and installed it yesterday.

I had to remove the SAS which was a PITA.
Followed instructions in the HOW and was doing great until re-reading and noticing the Edit at the end.
Had to remove the throttle bodies again to add the intake vent connection.

Anyone tell me what purpose the intake vent connection serves, pressure balancing?

Once you have the air box off there is lots of room to work and installing the Rottweiler is pretty straight forward.
I was worried about water splashing up and heat coming off the engine.
I made a prototype barrier under the Rottweiler base plate out of aluminum flashing.

Put everything bad together and the bike started fine, no SAS FI faults.



Looking straight down to see flashing in front of filter


Once I get the flashing dialed in I use slightly thicker material and add heat shield.
I'm also thinking about raising up the glovebox base about 1/4 inch.
This would form a slot all the way around the glovebox mask to allow air in.
Should work even with a tank bag.

I have a 2 into 1 with Akra with quiet insert. This ran fine with the stock map. I'll give that a try but will be learning how to use Tune ECU shortly.
