Hello there! I'm new to this site and so far it looks great! I'm thinking about getting into racing and was wondering what engine mods other than the usual (filters, pipe, re-mapping) tricks that might really work well with this particular engine. I also own a 2003 ZX9R, and when riding with other 600's with the RR, can notice that the RR is down a little bit on power. "SportRider's" dyno chart shows that the bike is down aprox. 5hp. Anyone have any ideas?? Thanks!!
