With the centrally fitted barrel, you'd have to go past full lock to find the notch. Without looking at your setup any closer, my guess is you'll have lost the steering lock mate.

Are you using the SV barrel? If not you might end up with the usual anti-tamper problem. There is a resistor embedded in the barrel to stop hotwiring. The GSXR could use a different resistor. Just something else to bear in mind.
