piston size gpz 750

hello all ,i would like to know piston diemesions for the gpz 750 ,gudgen pin diameter ,deck height and crowm height .my problem is iam trying to find 69mm pistons to take my zxr750h1 p6 bike out to the 5% over size that many of gsxr lads are doing to get extra ponnies from there engines .Being the only regular kawasaki running out there i cant let the gsxr run away any info would be great cheers troy

GPz750 pistons no good for a ZXR mate - they are 2-valve pistons. They also use a 15mm pin, which may or may not be the same as a ZXR750 ? Stock GPz750 piston diameter is 66mm, same as the z900 models.

Good luck with the search, anyone building a kwakka motor to beat those spewzukis deserves as much help as they can get

thanks gosling1 next piston to check out know is the zx636 piston in a 1mm over bore i think these are a 16mm gudgen .i ahave tried speaking to sum of the piston suppliers here and they couldnt be bothered to go throw dimension sizes it seems to hard for them if its not of the shelf they have no clue cheers troy
