WOW 110 YS on a V2 Katana 70 it's sick! :-) well too much power for me, not to mention the vibs you gona' get from it, i think that a 91 will be very good enough for her, if a saito 100 does the job so awesome why not a YS 91.
And if you want even more power try the 30% nitro Helli Performance by Omega fuels, it will work like a Swiss Doksa clock.
