Shorter rear shocks?

[flynrider]

Be very weary of speed bumps if you do this. I have to avoid them as it is because I will bottom out the CAT on them.
Oh...and you might be better served by getting a stock seat from Japan. They are lower to begin with (short people over there don't ya know) and that would make it easier to sell on later if you so chose.

So, it's not just me. I noticed that my CAT scrapes if I ride out of my driveway onto the street at an angle (and it's a fairly gentle slope). Last week I came up on a speed bump in a parking lot and made sure to go nice and slow but still ended up with a light scrape.

This is my first bike with a big CAT sitting under it and the first bike that I had to worry about bottoming out under relatively normal riding conditions.

I +1 Randy's suggesting to lower the seat instead. You can buy a lower seat, or have a local upholstery shop shave some foam off of your original and recover.
