Not a chance. You will still be 300-500 cc less than everything else in LW
I think we have done this before, but, what the heck - its a new year...
Liquid cooled, 4 valve per cylinder motor = much better than air cooled 2 valve motor. It isn't just displacement, it is about the potential to be thermally efficient. There is no reason that a well built SV superbike, with sufficient investment (money and development) can not be more potent than the other built LW superbikes.
Realy, I don't think your problem is cubic inches, it is cubic dollars. Feel free to spend more if you want to keep up.
