1015cc is safe.
Personally never seen a 990cc piston kit, but maybe one of the older gents has.

No eBay APP ID and/or Cert ID defined in Kunena configurationI take it you are looking at this one?



For the money (unless you live in Australia) you might like the extra kick from the higher compression the Wiseco 1015cc kit gives you. If you change nothing else it does give a noticeable change in "spunk" to the engine.
