I was under the (mis)apprehension that Z900 barrels couldn't be bored to 1075cc, (72mm) but the Wiseco specs suggest otherwise.

What is the general consensus? Is 72mm a bite too far?

If not I need as set of 1015 barrels

The Wiseco catalogue is slightly misleading.
900 barrels won't go to 72mm, there would be no liner left.
You need the 1015 block or buy a 1075 kit with liners and have the 900 block bored to take them.

Thanks Rob

That was my belief
