hello i would like to ask if someone out there regarding my problem. i have malossi nikasil 70cc cylinder now i need to change my piston kit due to loose compression. my problem is that the only available 47.6mm piston kit from where i am is for a steel block, is it ok to use a koso 47.6mm piston kit into my malossi nikasil cylinder? has anyone tried this? my scooter is on a mild tune only we even added based gasket to lower the compression for this cylinder. btw the koso piston kit is also a single ring.
thanks a lot
