tim1982 Posted February 6, 2013 Posted February 6, 2013 Hi there, I've got a SR125 and recently it's developed this problem of only seeming to run when the fuel tap is in the reserve position. When I try to run it from the on position, it sometimes won't start or if it does it will tick over but when I apply the accelator it cuts out. However, it runs fine in reserve. I got it running in the on position the other morning but having gone about a mile it suddenly started to lose all power and eventually cut out. I really don't have a clue what to do.

slice Posted February 6, 2013 Posted February 6, 2013 Hi Tim Welcome to the YOC, it's usual to do an intro before asking questions but perhaps you could do it later. Have you checked to see if the filter in the tank is blocked? Take the tank off undo the screws that hold the tank tap in place and pull the unit out, check to see if any of the tubes/filters are blocked, needless to say empty the tank first before you do this as otherwise you will have fuel all over the place. Also check all the pipes that feed fuel to the carb to make sure they are not kinked, just one other thing I can think of at the moment is the fuel tank filler cap air hole blocked? Try running the bike with the tank lid off or open. Hope some of that helps.
Moderator DirtyDT Posted February 6, 2013 Moderator Posted February 6, 2013 Intro aside, unless the fuel is low, the main fuel tube is probably blocked with junk. This is is the tank. Take the petcock off and clean it or get a patten one and refit it. Don't forget to empty the tank first.

blackhat250 Posted February 6, 2013 Posted February 6, 2013 If its a gravitypet cock, i find its the reserve filtre that clogs first, as its lowest among the crap,
