Have a 2007 RK Stdr. Bigbore kit, Thundermax ECM, Rush 1.5" baffles. Run 92 or93 octane or the bike just pings like crazy.
Started with 2" baffles--- too loud. Went to 1.75" baffles.... better and the engine smoothed out some. Went to 1.5" baffles and the sound is right and the bike runs considerably better than with either of the other larger baffles.
Just my observation.
