About big bore kits on a RZR 1000. Your RZR 1000 is 999cc from the factory. There are 3 different big bore kits available. -The first is a 96mm/1065cc big bore. This is the most economical as it uses your OEM cylinder. Also a 96mm will work great with your OEM rods. -The second is the 98mm/1102cc. This kit requires rods. The OEM rods will break with any piston over 96mm. -The third is the 99mm/1132cc big bore kit. This is as big as you can go on the 1000. You will need rods. We prefer the 98mm as it has more material between the cylinders which keeps the head gasket sealed. We do not recommend this kit for turbo setups. Core charge options for this kit: (We need your cylinder to make the next customer a cylinder). 1-Send us your cylinder we will then send you a big bore kit. 2-Pay the core charge of $399. We ship your kit. Send back your good cylinder core and we refund your $399 complete when we receive it. 3-Purchase cylinder with no core. This cost $399. Since you are not sending your cylinder back there is no refund on this charge. About your core. Your core can be damaged. We typically see people purchasing this kit who have ingested dirt or ran low on oil damaging there cylinder. As long as the scoring is less than 2mm you cylinder should be a good core. If you have any questions please call us.
