hi!

recently I registered on this forum, but I been reading some time before.

I need a little help, I looking for gpz 400 piston rings, engine ZX400DE-040766, a friend mine told's me this item are discontinued, this is true?, do you know about aftemarket replacement?

regards

Bruno


sorry for my english gramma

They are. Your bore (assuming it's the GPZ400R IL4) is 55mm. About your only option is to over-bore and fit 57mm pistons from a ZXR400, just bear in mind the ZXR has a 3mm shorter stroke. Or just stick a ZXR400 motor in.
