Hi my ybr 125 has just had a new fuel pump . But now she idles fine but when I touch the throttle she dies down and cuts out . Sometimes I can get her to revv all the way if I do it slowly . Any ideas ? Also my mixture screw ( if that's what it is called ?) is completely worn down ? Anyway to change that or do I need a new throttle body ?

Sorry I have just done so . Thanks

Hi every one I've just got into motorbikes and have joined this forum to learn about my ybr 125 . Then hopefully in few years time I can pass the knowledge on . Thanks .

Hi everyone . I am a new rider and have brought a new fuel pump for my ybr 125. I fitted the new pump everything was working fine. Then I went to go out on it today and it wouldn't start . I took the fuel pump out and the little o ring that goes on the output side of the pump had split . Causing low fuel pressure . I have got a new o ring where am I suppose to fit this o ring to stop it splitting . Last time I a pushed it on the nossle then forced it into the plastic casing . You could see it still half in and out . But i couldn't get it inside the plastic housing with out it distorting or getting crushed . What's the correct procedure for this o ring ?
