Hyosung GT250R not starting!

Don't make a habit of hitting the starter button while the engine is running, this is bad for the starter and engine.

Don't jump to conclude the starter is a problem untill you've checked the electrical system out properly getting voltage readings.

The worst way to fix a mechanical problem is to start throwing parts at it hoping something will work. You can get a multimeter for less than $20. This tool will be very valuable to you now and in the future.

Can't agree more. I fix Motorola cellphones for a living and sitting with about R100 000 (+\- us$ 70 000 ) worth of equipment(scopes and spectrums) on my bench but finding about 80% of my faults on the phones by just using a normal multimeter.

Thanks guys.

Don't worry, I wouldn't hit the starter usually while the engine is running, but I know it would have some kind of slipper/clutch mechanism, and hitting it once or twice wouldn't have hurt it.  Just part of trying to ID the problem.

I'm thinking the fuse is a worthy contender here (hoping), but just have to loosen the bolt holding the little box above the battery there (I assume that's where they are) - it's on really, really tightly!

And I already own a multimeter, and know (mostly) how to use it. Just haven't had the time to go over this properly yet! Thanks for the replies :)

I think it can be a problem with the start button, the kickstand switch or maybe with the start relay.

It wouldn't be the kickstand switch, as I wouldn't have been able to jumpstart it.

I do however agree with you on the start switch or related circuit... is the start relay one of those two small 12V boxes above the battery?

being able to jump it sort of takes the start button, relay, and kick switch out of the equation. That is aside from the random gremlin that only causes problems from time to time.

My gut still says voltage issue, ie battery or charging system...

I don't understand how jumping takes the starter system out of the equation. I'd really appreciate you explaining that if you have a minute.

I would have thought that being able to jump start it.... oh hang on, I used the wrong terminology. I roll-started (dropped the clutch in 2nd), I did *not* jump start it (there was no battery involved). Surprising no-one else pulled me up on that actually.

Thanks :)

Well that certainly changes things :)

I think its a bad seal on the flux capacitor.

Seriously till you get some testing data it's really pretty hard to make an educated guess.

Takes 2 mins to check voltages with a multi-meter....

Re: the flux capacitor - I just had my Mr Fusion unit serviced with the last oil change, so I doubt that's it. Besides, it's a 250cc right, how often am I going to be doing 88MPH?

Also, what are the nominal OFF and then RUNNING voltages I should expect from the battery? Thanks!

Battery voltage 13+ at 6000 RPM.

lower RPM you are not getting much.

non running should get at least 12.95 volts or you have a bad battery.

Some definitions:

PUSH START:
This means pushing the bike and poping the clutch to start the bike.

JUMP START:
This means using some other battery to start the bike.

the flux capacitor:
that thing between your ears?
