A: No. You would need to run the cylinder that the piston was designed to run in, otherwise you risk damaging the bike beyond repair.

I have a 1998 500cc 4X4 quad arctic cat with a Suzuki engine ,need piston kit to increase to a 600 or 700cc can bore out jug to fit

A: Unfortunately there will not be a piston readily available to bore this model out to a 600cc or 700cc machine. You will need to have a machinist look at your cylinder to verify exactly how large it can be bored out to. From there you can send the piston to a manufacturer such as Wiseco to have the piston made in the correct bore size that will retain the correct pin height and other critical dimensions.
