if you moved your SAS you shouldn't keep your cat. the O2 sensors wouldnt make any difference as it will just make the bike run in open loop all the time which is ok , less rattle, more smooth, more petrol consumption.

What do you think? How many kms/miles have you done without o2 sensors and with cat?

990 is a completely different bike

Is it not the job of the CAT, to ignite and burn unburn fuel, the SAS system lets air into the exhaust to facilitate this action. as for catching fire, it would need a consistent supply of unburn fuel i would have thought. Flames look cool tho, coming out of exhaust pipes.
2016 1290GT-remus link and muffler, 2010 Black 1200 Multistrada full Termi system with mapping, 2005 SMR 640, full Titanium system, Mikuni flatside racing carb, 2 sets of wheels, 18 litre tank, and a nice soft seat.

Just had my 2016 GT mapped on a Dynojet 250, my bike is stock with a Rottweiler intake and 80mm stacks,pvc5 results were 149 hp and 90 ft pounds at sea level . Dyno tuner has lots of experience says that's normal for the Superdukes he's had on the dyno. Says with pipe I could expect maybe 10 hp and 8 ft pounds more.

I think there's a lot of happy dyno's out there :mrgreen:

Hi all,

I’m new in this forum, but want to comment a bit. I had earlier 990 / 990R - > SD1290 and reacently SD1290 v.2.0.
My plan or target was flat torque curve. So what I did was De-cat pipe, Rotty + 80 (1pcs), pcv + ignition module, Akra slipon.
Torque curve is nicely rising no bumps.

Welcome Jay60 and thanks for sharing that data with us. That's a text book torque curve and you did a great job there.

Thanks AllanP,

Lets see what is the result when I get the new 1290R done, but that will be late February when its more or less ready. I have ordered Rotty, 40 / 80 TVS, PCV + IM, Bodis de-cat, Akra and thinking of Hi-Flow cat but...

Overall, I recommend PCV and ignition module with Rotty or MH air box, for those one´s who are looking for flat torq.

Cheers
