Petrolhead 0 Posted April 10, 2005 I've just found out why my nitro engine doesn't work, so I am after these parts: A new Kyosho GX-15 nitro engine, or it can be very lightly used but UNdamaged OR These parts for the GX-15 engine: 74015-02 -.15 Cylinder and Piston Assembly, 74521-04 -Connecting Rod, 74015-03 -Piston Pin Set, 74015-15 -.15 Gasket Set 74521-07 -Ball Bearing (large) OR A different engine (new/lightly used) that will fit my Kyosho ultima GP Buggy. Thanks very much, Allie. Share this post Link to post
