It should be a nicasil liner,they can't be rebored, they can be re plated. Langcourt is very good, in the uk

Don't you *have* to go bigger with a rebore? (even if it's a tiny measurement)...?

Ye i was gonna go to the next size up,
I've seen all over the net that banshees can be rebored noting mentioned about replated or sleeved

This wat i found its the piston sizes that can be bought
64.00mm -347cc standard

.020- 64.50mm =352cc
.030-
.040-
.050-
.060-
.080-
.090-
.100- 66.50mm= 382cc
