ZX12 injectors are ~330 cc per min.
1st Gen Hayabusa, GSXR1000/750/600, are ~245 cc per min.
2001 Hayabusa turbo with stock 245 cc injectors made 260 hp on dyno but had to shut it down at 9.5k because it went lean. 370 cc injectors solved that problem.
I think the fuel pressure was around 70 psi, and the 245 cc is at ~40 psi, so that is probably why the Busa made so much power on the stock injectors.
