if anybody can help with these it would be greatly appreciated.

Do you mean a kit piston? The standard RS125 pistons are domed. Only the kit pistons are flat. Kit pistons have a flat top, thinner ring and the piston ring pin (gap) is straight in the back. The stock piston has a domed top, slightly thicker ring and the gap of the piston ring rides btween the back boost port and the left rear transfer port. I think the HRC number for the piston is HRC-NX4-0201. The stock piston is: 13100-NX4-780. Need a kit cylinder to go with your kit piston? Got 3.

A friend told me that he needed a flat top piston and hasn't given me any details. I will ask him some more details and find out. I can't remember but i believe he wanted them because of the way the squish was setup...maybee i misheard.

Like i said i will find out from him. Thankyou for you input http://www.tz250racing.com/iB_html/non-cgi/emoticons/smile.gif

Ok i just had a chat to him - He has the JHA kit cylinder/head, so we need the JHA Kit piston/ring, and 2x .5mm base gaskets to suit.

If anyone can help us out it would be greatly appreciated.

EDIT: Its a 2003 model also.
