i race a zxr 400 in club racing and the tunning limit allowes us to bore the barrels out to manifacture tollerances
i read up in the zxr400 manual that it is a 0.5mm over bore is what kawasaki allow but that was back when the bike was first built , since then kawasaki have brought out a 1mm overbore piston .
what i would like to know is now the 1mm piston is about dose that mean kawasaki have set the manifacture tollerances higher ?
I would check it out with your local club officials on the interpretation of the rules. If Kawasaki now offer a factory part that is larger, then I would say that this should be able to be used.
kawasaki ONLY do 0.5mm oversize it woz bemsee that let u hav a 1mm over size piston so then people had them made dynotech stock them but i think your find u cant race with them any more at club level so be careful wot u buy mate. #17 f400 team chicken chaser
