RC valve

[Finney2003uk]

also anouther question u no the RC valve on the nsr 125 f s should it be up or down if u no what i mean unscrewed or screwed which way opens it and does it make a diffrance if up or down

[alains]

the valves are piloted by a servo-motor which is controled through the cdi box . look on your right side , you can see the cables . start your engine , then put up revs and you will see the pulley turning anticlockwise for openning the valves .
i join you a copy of how it works

so how do i turn it up so it will make me bike faster lol tight or unscrew the lead which go in to the rc valve or some thing else

[alains]

this is because your valves do not open fully and also because a poor compression (6,8:1) , rough surface transfers and not enough volume of mixture . to do a better openning of the valves it's a very simple thing to do : take off the screw in the middle of the pulley (on right of the tank) . lift up gently the pulley . pull the right cable of its stop (do not pull out completly) . take a piece of aluminium paper and turn a bit around the cable and refit the cable by pushing it firmly . take it of again and verify if the thickness is at least 1 mm and max 2 mm. this make the cable pulling more .
that's all .
i recommand that you read the topic RC valves control , put yesterday and tell me if you will be interessed . finally if you want to know how to boost it , ask me .
