A run on the bike is always good therapy!......all too familiar with being an oddball head case lol and issues with meds :-(
Hope things pick up for you soon.

Cheers Massimo,

I have been wondering if there was a simple way of getting around the canister dongle and after being off the forum since mid January (it just died and some UK & Aus & NZ members just couldn't log on), I log on and there is the solution ........ :D

I wasn't impressed with the freight costs from the USA to Aus...... the dongle/resistor in a connector was cheap, but the freight to Aus was $70...... ouch....... so I was thinking of another way to do the canisteremectomy and saw your post 8-) .

Many thanks :)
Ciao Aussie, happy to be helpful somehow.
I made some further research in the last days .... it has been initially difficult because if U unplug the Evap valve (or probably any other non-vital element connected to the harness) and start the engine, the related Engine Check caution light turns on but even if you plug the part back it stays on for few more start cycle (probably 3 or 4, not sure) so if you are trying resistors with different values the trial & error technique is definitely not the fastest way to go.
Long story short I made some web research and some math and I came up with a solution that works: 400Ohm resistor of at least 1/2Watt.
In the pic I'm running an adjustable resistor 0-500Ohm, 67W set on 400Ohm. .... with a really ugly yellow/green tape!!!
I will get soon the correct resistor to plug directly on the connector and I will post some pics
....un saluto!

I removed the charcoal box from under the seat to get space and just put some cloth over the ends of the 2 tubes held by a rubber band! No issues at all no engine lights or strong vapour smells either.
Been like this for about 1500miles now👍.
The reason I didn’t want to remove the complete sas system is I like the pop and gurgle on the overrun.

Cheers guys......

I'm still waiting for my 'dongle' from the UK via the Royal Mail...... :lol: (it's prob in Aus now and lost in the AusPost system).

Massimo's 'loop the hose' makes a lot of sense, but i thought i'd buy the dongle so i could leave the hoses in place in case i ever had to return it to oem...... you never know what the thought police are up to these days in Aus ;) .

I think I'll plug the vacuum hoses up stream of the check valve....... though, with the dongle attached, the unpowered canister valve is probably a good vacu-plug anyway.

I think the fuel hose (tail) can be plugged too as there is a 'Y' piece & hose down to the sprocket for any fuel vapour leaks.

I might re-use the hose connector tubes from the canister connection to convert the canister valve hoses into throttle body synchro points - just like the Rottweiler stage 3 kit....... then my synchro's will be easier (cheaper?) to do or I can pull out my fluid manometer and do them myself in future.

I'm so glad I didn't order the little dongle from the USA (the freight charge was $70Aus... :shock: ).

Sorry but I don’t think that’s the best way to do it. The hoze coming from the right side is pulling air through the canister that is an air filter by the vacuum of the manifolds. If you open the circuit you let air “not controlled” to enter in the inlet. If you don’t want to remove all the lines I think the better and easiest way is to unplug the canister and close both tubes separately then open the big vertical one on the left side beside the sprocket, drain it from water/gas collected and allow the tank to breathe freely from there.

Here the loop on the valve but in this way u need to close the 2 lines that go to the manifolds.

Here Front cylinder manifold port closed. Tube left for future throttle bodies synchronization and because way easier.

ciao, today I went to the electronic store and I discover that a resistor of 400Ohms is not that easy to buy; you can easily get 390Ohms or 470Ohms.....don't know way I'm not an expert on this stuff ....so I chose 390Ohm and it works fine! so I completed the installation with the help of hot glue and shrinking tubing....here some pics

Cheers Massimo & AndyW,

My error code eliminator showed up pretty quick.... ordered Feb20, arrived 6 March..... 8-)

I was just doing the Massimo 'loop' with my tank still on, and the postie rode up with the eliminator.....

I was thinking, the purge valve probably doesn't need to flow anything as it is vacuum driven, so it probably could just be sealed off with a couple of caps...... but I don't know - my eliminator went on in minutes :) and I removed the 'Y' piece and plugged the 2x vacuum hoses from the throttle bodies - they were long enough for tuning access.

So charcoal can is out, and lots of stuff can fit under the seat now.....

that's my solution.....I removed the canister and the big hose but I put a small one instead in the same position.....looks like my previous SDR 2014

...and left as are the 2 hoses coming from the manifolds for future idle alignment if required. The front one just plugged and the rear connected to my beloved chain oiler.

What would happen if you just remove the canister and loop the 2 pipes?

Well after much thought I’ve pulled the plug on ordering the Rottweiler sas and canister delete kit.
Tried the us website but the postage was as expensive as the product and the risk of customs tax.
Managed to find it on eBay from p3tuning at a more realistic price.
I will miss the noises on the overrun but the more I read into it removing the cat this emission system was doing nothing.

When you think about it, the purge valve would be allowing the vacuum from the throttle bodies to suck unfiltered air from around the fuel tank filler assembly. So removal, or the quick and easy loop of the purge valve, is better than letting any dust into the cylinder heads.

I found there was no need to extend the hoses for balancing as they are long enough to clear the tank. I think Massimo has some pics above...... I did the same, just plugged the oem hoses and tucked them out of sight.

As per Rotty site and other posts - the SAS only adds air to the cat converter to boost temp and function, so if the cat is gone..... the SAS is redundant.

Cheers mate.

G'day all,

Was down at my KTM shop this morning...... my purge valve dongle had burned out (causing some weird messages & warnings) and the tech had diagnosed "resistor needed on purge valve"....... so I handed him my oem purge valve to replace the crap dongle I had wasted $50Au on and he took the looped hose off and installed up under the tank (then deleted the "check engine symbol" warning). Bike running perfect as always, with no strange false warnings or dash symbols....... and he confirmed the battery has nothing to do with error codes or warnings...... so just buy whatever battery copes with your climate best.

I added the plugs to the valve ends but they are not required as the valve was vacuum powered and once those lines are disconnected and plugged, the purge valve acts only as a resistor for the ecu.

Yep done the Rottweiler sas and canister delete today, had to cut out a small plastic lug in th canister dongle to get it to fit. But everything seems fine no warning lights on start up.
I didn’t go down the Pcv route as I wanted to still have the 3 maps.
So I installed Remus de cat and sprint filter , I then installed a booster plug and boy it’s never felt so fast and pulls from virtually no revs

Took it out far a fast 30 mile blast running great power wheelies for fun now, but I do miss the crack and bang on the overrun now gone completely.
Just wondering if it will effect the fuel consumption?

Thanks to all those who posted probably past and present just starting to acquire all the needed bits and bobs but i’m Going the PC route having done the same on an X/R didn’t find I lost the other maps available ie rain etc.or is this a quirk of KTM??

Oh and going Motohooligan.
