I'm trying to check if my recently acquired gpz11 has a Wiseco big bore kit on it as there was a rumour it had. Has anyone got a picture of the crown of a piston from a Wiseco 1170 ? Some Wiseco pistons appear to have individual cutouts for the valves (4 per piston) and others just one cutout each side I.e. 2 per piston....like the standard piston :?:

I can't imagine a suitable piston with 4 cut-outs, as there's only 2 x valves per cylinder :??
