im in the process of building a motor its a small bore twin and they dont offer too much for piston selection, it has to get bored and i was goin to just pay the money and go with the wiseco pistons but the sled is already 7.9:1 and i dunno if i want too much more compression its an old rotax rotary just curious to see if anyone had ran the wiseco's ive herd some horror stories but its on 4 stroke quads/dirtbikes just wondering what kind of luck you are having with them.

they work fine. run them in all my mod engines........

the nice thing about them is they come ceramic coated .

I know first hand that their automotive pistons are really good.

no they don't.

do not used forged wisecos in a rotary rotax.
i ran wisecos in my srx race motors for a couple of years and nothing but troubles.
these motors were not engineered or designed to run forged pistons. go with cast pistons, you will be much more happy and so will the motor.
what type of rotary rotax is this?

Why would the Wisecos raise your compression??
