Bore a tb
Like it is already said - boring is not going to make you much difference.
The formula is: [bore (mm) X bore (mm) X stroke (mm) X 0.0031416] / 4
Stock TB bore is 72mm - stroke is 60mm = 244cc's
Largest Wiseco piston for the TB is 74mm ( 0.080" or 2.00mm oversized)
bore 74mm - stroke 60mm = 258cc's
You havent' gained much (14cc's) by a maximum bore, and you have wasted a potential 6 top end rebuilds out of your cylinder.
