So last few days I did some tests with and without filter cover. There is really difference in low revs where engine feel more live and better pulling. In high revs there is considerable more noise.

@Steve: Will do. But right now we have 15cm of snow here…

I think there will be definitivelly more rich sound in lower revs. KTM is offering somehow “open” airbox as stage 1 upgrade. Still compliant with EURO norm.  You can hear difference in that video on Youtube also.

Actually 701 Vitpilen get more if you open airbox.  https://www.youtube.com/watch?v=pG-nFDpbYwE

Does bar end Husky mirror works better then originals in high speeds? Originals work relatively fine up to 100kmph than there is only some blurry image.

I’am from Czech. 701 runs on 95 octane fuel. New bike with only 1600km

Same situation with same motor https://www.ktmforums.com/forums/duke/32177-new-690-duke-headers-glowing.html

Same on mine 701. As there is oxygen sensor I assume we have faulty one or it is supposed to be so. I will definitely contact dealer.
