    Can I use SBT pistons on a nikasil bore?

    I have a 97' Tigershark Daytona 1000 with nikasil bores and was wondering if your pistons and rings are compatible with them? You guys offer steel liners for my ski and didn't know if the ring package that is included with your pistons can only be used with them (steel bores).

    The pistons and rings don't care whether they are going in steel sleeves or nikisil.

    That is incorrect. Depending on what the rings are made out of, it does matter. As stated in the article below carbon steel rings with a harder chrome face are not compatible with nikasil bores.

    I've yet to ever see chrome faced carbon steel rings in a 2 stroke watercraft engine.......and I think I've had every make and model apart.

    Nikasil plating is expensive and I don't want to risk damaging my new cylinders because I overlooked the rings. Chrome rings are very common in 2 strokes and word on the street is to stay away from them when using a nikasil cylinder.
