dont think so... they are still 2v. "Desmodue" they say..Ok, I will confuse you even more. The 93 to 03 monsters (ie 600,620,750,900) have 2 valve motors. The s4 has a 916 4 valve motor the s4r has a 996 4 valve motor, and the new monsters (ie 800,1000) have 3 valve motors.
what norm fails to tell everyone is that he has a tlr 1000 that's naked AND water cooled...The importortant thing to remember is that the 4v motors are water cooled, & water cooled motors in a naked, monster stlye bike are for sissies!!!!
