As some of you may know I just bought a new 2009 RS.. I have done alot of reading on here an another site.. I came across a post about a POWER BAND.. I cant seen to find it anymore.. Anyway my question is .. What is the power band??? I know I use to have a 2 stoke dirt bike.. It had the power band, but I didnt know a 4 stroke engine had this.. Maybe they were talking about something else... Thanks for any info....
