A 450 may tolerate it, they're pretty forgiving.monseraat said:72 cb450. yea those are the exact ones i was thinking. would they cause the bike to run rich or lean?
My last three bikes have all had these on when I bought them. On the KZ they are just like Bill said, quiet under 5000, but the sound changes above. Not loud or obnoxious but a nice angry tone.tbpmusic said:Another choice is the RoadHawk, good look, quiet at lower speeds but get authoritative at about 5,000 rpm
