I am in the process of rebuilding a 09 RZR 800. I am rebuilding the motor since someone killed a rod bearing and since I had it apart I replaced the crank (rods and bearings), cam (upgraded to an S cam) and pistons (Figured it was apart I might as well replace them) I noticed a slight mark in the top of the cylinder bore in the nikasil. I am wondering if I should just run it , replate it or replace it. Not sure what the best option is, seems like a new jug runs around $425 or so and replating is around the same. I haven’t seen many used jugs for a reasonable price so I am not sure what to do with it at this point. The mark in the nikasil can be felt with a finger nail and is just it the top of the stroke about and inch wide by 1/16" down the cylinder.

Thanks for any suggestions
