My hyosung will not idle then once switched off will not start

I have purchased a hyosung 250 comet with less than 1000km on the clock it is a 2005 model but has been sitting around for a couple of years. I have changed the fuel and plugs, blown out the fuel lines and carbs with air. now it starts first try in the morning but will not idle. if I stall it due to not idling or turn it off, it will not start again until the following morning. please help is this fuel or electrical issue?

Hi and welcome to FixYa,

Initially and based on your description, this pertains to a fuel issue. Corrective action would involve not only changing the fuel but cleaning the fuel tank, the built-in fuel filter, the fuel valve, the carb. Particular attention should be given to the jets and the multiple pin holes.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Wiring hot wire ignition diagram


Take proof of ownership and your serial number to your dealer. They should be able to make you a key. If they cannot, you can purchase a replacement switch and key. Hot wiring the bike is never a good option.

2004 hyosung 250 comet wont start


Sounds like there is too much of a load on that circuit. You need to do a battery/charging/draw test first and foremost. You can normally have these tests performed for free at your local auto parts store. It could be a bad starter pulling too many amps for that circuit,or it could just be that the valves need adjusting. But get the battery/charging/draw test done first,and that should point you in the right direction.If the tests come back in spec,..then i would start looking for a bad ground,or a pinched wire.Especially around and on the handlebar controls.

How do i drain old feul from the carburettor of a hyosung gt 250 comet???


Hi, you could remove the drain screw from the bottom of the float chamber, this is the lowest
Point on the carburettor, however if u are having running problems, the best thing to do would be to remove the carb-s
Remove and clean out the float chamber including the main jet pilot jet, and choke tube,

I was looking at a 2005 comet 250 4 sale and noticed engine paint seemed to be flaking off is this ok and can it be tidied up some how,other wise pretty cool bike.


Paint flaking of is cosmetic only,,,If you want to take the time too paint it,,youll need to clean the erea,,make shure there are no oils or other dirt on the motor,,If it needs to be sanded to smooth the surface so you dont have a dip in the paint then use 600grit,,,,re-clean the surface again,,,Use 500F engine enamel,,,Dont just do a little spot though as you really want too match your paint surfaces.

Digital clock resets to 12:00 every time I switch off the ignition.


Have you taken the clock off? If so you might have incorrectly connected one of the leads to the wrong power source. You need to have a constant power supply to the clock for the memory but the clock light needs to be through the switch so that it will operate only when the ignition is on. If you work your way through the cables you should hit paydirt. Most source wires are the same colour as the cable of the accessory, but not always. To find the wire supplying the memory, switch your bike on and one by one disconnect the couplings reconnecting them as you go until you lose the readout. That is the one. Now you need to find a constant power source. Switch your bike off and look for a likely cable. Once you readout comes back that's the one.
