RKT sells a very nice piston only kit, dual ring, coated, that's what I'm running. Millenium recoated my cylinders, not nic, a Ni-Com, supposed to "absorb" oil, has worked awesome so far! Check your reeds for delaminating boots, have your crank checked(did mine locally) for seals. Basically spend a little more money and have everything checked over so that something simple like a delaminated reed or a bad crank seal doesn't take out the motor. Worth it in the end!
If you need cylinders nic'd and are willing to spend a little bit, check out either RKT or Big John for engine kits, usually pistons, head, gaskets, misc. Seem a bit more expensive but are not outragious in the end, and they simply build power.
