tez73 Posted March 16, 2011 Posted March 16, 2011 hi am the unlucky owner of a yamaha sr 125 that i fitted a new throttle cable too now its over revving, my pl ug was dark brown when i brought the bike, so i moved needle setting from middle to the bottom one. i have also made sure the cables not snagging on anything and its not quite as bad now but its still very high and unrideable! any ideas?

Hi tez73 When you say the bike is ‘over-revving’ If you mean as soon as you start the bike it goes towards full revs, Check that you have fitted the throttle slide into the carburettor the right way round,If the carburettor is similar on my DT then it is possible to get it in back to front and as a result the slide is pinned half open. Might help
root Posted March 16, 2011 Posted March 16, 2011 Also reset the needle & check the air filter , clean & re'oil or replace it
Moderator Airhead Posted March 16, 2011 Moderator Posted March 16, 2011 You fitted a new throttle cable, perhaps you routed it badly, also check the end of the cable (the ferrules) are seated properly at the twistgrip and the carb,
tez73 Posted March 16, 2011 Author Posted March 16, 2011 You fitted a new throttle cable, perhaps you routed it badly, also check the end of the cable (the ferrules) are seated properly at the twistgrip and the carb, just changed filter a couple of weeks ago, yes it goes straight full revs. thanks for the advice will try again in morning and let you know how i get on!
tez73 Posted March 17, 2011 Author Posted March 17, 2011 hi chaps i got a second hand carb and fitted it and now it runs sweet, well about as sweet as a sr 125 will run!! the carb float valve that regulates how far float bowl goes down was broken and hanging off.and just in time to watch england vs west indies in the cricket world club. life is sweet again for at least the next 5 minutes. thanks chaps for all the posts and advice very welcome, take care.
