This is an older - style piston with fewer rings. Rings are sold separately. The ring size should be 0.005 to 0.010 larger than the piston size. For example, if you have a 52.10 piston, you'll need a 52.20 ring.
To use this piston, first make sure to select the right - sized ring as mentioned in the product description. Install the piston carefully into the cylinder of your Yamaha engine. When fitting the ring, be gentle to avoid any damage. As for maintenance, regularly check the piston and ring for wear and tear. If you notice any excessive wear, it's best to replace the parts. Keep the piston clean by using a suitable engine cleaner. Also, store it in a dry place when not in use to prevent rusting.
