flash_bob Posted June 20, 2007 Share Posted June 20, 2007 Hi, Just bought a 98 SR125 with 6,500 on the clock so i can get some experience on the road and pass my test and then get a real bike. Have changed the plug and the oil. Does any one know proceedure for adjusting the idle speed. There is an adjuster under the carb which i beleive has to be open 1 to 1.5 turns and there is another slow running adjuster near the choke. Even though it appears to be idling ok it does cut out sometimes so am not convinced i have set it up right. What do the 2 adjusters do? Appreciate any help as i am very new to bikes. Thanks Link to comment Share on other sites More sharing options...
qtws Posted June 4, 2008 Share Posted June 4, 2008 Hey there, Mine's a '97. Adjuster underneath carb on engine side is the mixture screw. 1.5 turns out from fully in. As its on the engine side, its a fuel adjust. On the airbox side, it would be an air adjustment screw. Same function in either case - to ensure you have the correct mixture The adjuster on the side controls the throttle slide height, and thus tickover speed. 1.25 turns out from fully in (YMMV here).
