you Will need a new head gasket to change your piston rings, available at your local Honda dealer.
The first thing that you need to start changing your piston rings is a 10mm ratchet, this is to take off the cylinder bolts.
once you have the head off
you can see the piston and a mark on the top of the piston reading EX that stands for exhaust, this marking has to be facing you exhaust flange. there will be carbon build up on the piston so the marking may not be readable until you clean the piston, i recommend carb cleaner then washing it off with water.now you are ready to re move the cylinder, just pull on it until it comes off, your base gasket may make this hard to do because of your base gasket sticking to the cylinder.
once removed you will see the piston connected to the crankshaft, stick a clean rag into the crankcase to make sure no foreign debre falls into the crank case.
next you will have to remove one of the clips holding the piston rod in.
once removed get a flat head screwdriver and push the rod out of the opposite end of were you remove the clip.
once out you will be able to remove the piston.
there will be a little Bering inside of the loop were the rod went, you will be able to see once the piston is out, just slide it out and check if its all there, then slide it back in.
the piston ring should be seated in the groves in the cylinder, if you inspect is closely you will be able to see a rise in the piston rings grove, this should line up with there the piston rings are slotted.
then you will be able to slide off the top and the bottom piston ring, you slide it off up so it you don't score the sides of the piston. there is a difference between both ringe so know which on is top and which on is bottom, the top is more silvery that the bottom in new rings.
then you will be able to slide the new rings right on. they will flex a little before settling in there rightful groove, remember to put the bottom ring on first.
you will need to oil your rings before you slide on the cylinder, making sure that the piston ring slots are at the piston grooves, hold the piston rings tightly to the piston while sliding on the cylinder, for a good seal without getting a new base gasket use gasket sealer to make the seal perfect, make sure not to get any into the crankcase. one your cylinder is on it is as simple as bolting the new head gasket in in place of the old gasket and you are good to ride!
