Have you checked the engine yet tony, the code is above the chain stamped on the engine, if it's still the eddy engine it will be stamped 990rr , where as standard engine is 990rp ------------- current;2001mille,2003R,2003Eddy,2012Tuono. Previous RS250,2006Factory,2001mille,2001R and 2x2002mille |

Yes mate, as far as i know the 990rr engine and 57s are bike specific to the edwards, i think the 2004 rsvrs are stamped slightly different, something like rr990 and the 57s have different coloured connectors, but someone on here may correct me about the 2004 specs. ------------- current;2001mille,2003R,2003Eddy,2012Tuono.
