Danny,

Measure the outside of the sleeve. The older NR's use a sleeve of .756 OD and are generally the 1990's models. The newer ones have a sleeve of .767 OD. You need to know which one you have. The piston OD is the same for both.

Glenn Quarles from TX is the US distributor of the NR product line and is on this site.

Mark Leyde (AKA Lights here on IW) is the US importer of the GO engines which are a clone of the NR's. They have parts that interchange with the newer NR's and includes the pistons at .767.

New P/S sets for the older version (.756) are hard to find. May have to get a new engine. NR's can be had for less than $300 and come in 5 or 7 port configuration and many other engine options. The GO can be had for about $200 and comes in 5 or 7 ports.
