SMR511 - Problems after secondary butterfly removal?

Hi Everyone,
This may be a strange question... I have a 2011 SMR511. ~7000 km. I've ridden a lot on the streets, as well as several hard SM track days.

Aside from a failed stator right when I bought it (brand new), I haven't had any real issues. No flame-outs, or anything like that.

I've read a lot on this forum about how great the butterfly removal is. So I'm considering doing it. But has anyone done it and had it actually CAUSE issues on an otherwise stable bike?
