Is it known how closely the busa caliper bore size matches the stock caliper bore size?

Good Fortune!

I'm using an stock rear master with a Bandit rear caliper (same thing as a Busa's) on my 1000.
It seems to work OK, but then again I'm using rearsets that use a linkage setup and shorter than stock brake pedal.

On my 900, I'm going with a Gsxr1000 caliper and master cylinder, with custom mount.

Later, Doug
