Boring barrels

#1 PostAuthor: RALPHARAMA » Thu Oct 15, 2020 9:02 am

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 :roll:

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.
