Photo Info: Suzuki RM-125, RM-250, and RMX-250 Exhaust Power Valve assembly schematic. I thought that some of you might be able to use this diagram/info. ***My 2000 RM-125,..Power valve adjustment: 1-turn clockwise from zero tension..this is the stock setting,..I adjust mine to 1-1/4 turns clockwise. *[more turns clockwise adjusts it to have more tension..hence the valves open later..giving you of a longer lasting/usable powerband]. **use less tension for more top end.
