Hard starting Hyosung

**<Rhino>** · 25th June 2008, 19:26

I have a Hyosung GV250 and find that in the morning when the bike is cold it is very hard to start.

What happens: I press the starter and it just sort of spits and hisses but dosn't seem to want to fire, if I add a small twist of the accelerator it doesn't even spit or hiss it just sounds like it flooded and does nothing! release the accelerator and try again: spits and hisses etc, eventually it fires a bit then stops and after a couple of minutes of trying it might fire and if I very very gently twist the accelerator it will rev but if I twist too much it will die, when it re-starts it sounds deeper like its flooded and will eventually fire and rev away as normal.

If I put the choke on it just wont go at all, like its flooded??

I'm new to this so any help or advice will be greatly apprieceated

Thanks in advance

Use the choke on the first start, leave it for a little while, while slowly sliding the choke back until you hit normal idling range.

Just gotta let her warm up.

Use the choke. If that doesn't help, take it into the dealer early in the morning and say you are having problems starting it from cold and explain the problem... They will almost certainly have a solution for you.

the technique is to crank it first without the choke...it will cough and die. Then apply the choke and crank again. This should stir some life into it. If that doesnt work...then off to the workshop!

stop trying to start it - something is wrong. You will damage the starter before long - it is just not constructed to handle that sort of treatment. Take it to the shop and leave it there overnight so they can start it from dead cold and see the problem for themselves.

How many km's has your bike done, and how long has it been since a service? Last time the spark plugs and air filter were checked?

**CB ARGH** · 26th June 2008, 09:49

This definately doesn't sound good. Like DB says above, get it checked out professionally. You don't want to have to fork out for new parts.

It's just cranking the engine, how is that supposed to hurt the starter? It's doing exactly what it's designed for. You'll get a flat battery in a hurry though.

How good is the battery? Cold weather like this it's hard work starting an engine; if your battery is slightly shit then you'll have enough juice to crank it but not enough to give you a really good fat spark. Might need to refine that choke technique too, every engine likes something different. Shouldn't need any throttle starting, four-strokes don't normally like throttle when starting.

Thanks for the replies.

I don't know when it was last serviced as I have just bought it privately, actually I need to ask that don't I.

This morning I used used choke only, no cranking of the handle and it kicked over after 3 bursts on the starter. Heap better and far less cranking than is has been.

Hopefully that's just it

At some point, grab a multimeter and tell us how much voltage the battery has got. Throw a couple of spark plugs at her too, can't hurt, most plugs are about $6 each and there's only two pots.

nah you can't run a starter continuously for two minutes. Well, you can, but it won't last for long. Starters are meant to run for a few seconds maximum and then they last for years and years.

From dead-cold with the choke on full, and a very small opening on the throttle, it should start in a second or two. If it hasn't been run in a week it might take 3-4 seconds.

If you are still struggling with it, get an old hand to show you.

There is a trick to starting every bike. Get to know yours, and you'll get it to go first time, every time.

Thanks DB, tried this and it works a treat, that simple.
