Hyosung 250 wont start

[filson445]

I was stupid enough to let my wife get a street bike, which she rode for about two months and suddenly became scared of. I want to sell it but when I went to start it up the battery was dead, no problem charged it, still nothing, bought new battery, light came on but wouldn't start, charged it the next day went to start it dead again. There must be a short somewhere. Any suggestions. The bike is a hyosung 250cc----

I STRONGLY suspect that your problem is NOT with the battery but with the cables (or maybe solenoid or starter switch). Check the "OTHER" end of both main battery cables; might be loose or corroded.

Another "obvious" check is the neutral switch, sidestand switch, clutch switch and kill switch. Any one of those can stop the starter from turning over with a perfectly healthy battery...........so can a blown or loose fuse.

Need to put a meter on the battery to be sure.

Thanks I will try those. I do now know the battery is bad. That's taken care of. However I just dragged the darn thang out again w/ new battery and I can hear the starter spinning but it will not turn over.

Well then I guess it is NOT "DEAD", is it?

Sheesh!

Previous advise is moot.

[filson445]

why would you hear the "grinding" starter spinning but not turning over/

Faulty starter, starter clutch, solonoid not fully engaging....take your pick.

They have started selling Hyosungs here recently and FWIW I reckon they are a peice of cheap ...t. I suspect they will improve over time but as the saying goes "you pay your price you make your choice" IMHO.

stupid question: are suzuki gz250 parts interchangeable? If not can parts be gotten in u.s.

Looks like you are doing a lot of WILD guessing here; not good.

What makes you think your bike is in any way similar to a GZ250 ???
My guess is NO, they aren't the same at all but that's just a guess.

For parts: Find a dealer? Ask the person(s) you bought it from ??

[Aussie Steve]

I believe the Hyosung is a copy of a GZ but that is where the similarities end. I have seen Chinese copies of Honda engines and they are inferior in every respect so I suspect the Hyosung is the same. Swaping the motor over is a better option.....but then you would have to explain why to any prospective buyer.

If you read the post it says the battery was dead again.

no guessing the bike was copied from the gz was just a thought. How do I test the starter to pin point it. It has been 20 years since I fouled with a bike.

Try getting it to start by using jumper cables and a car battery.

Assuming the bike is a negative ground:

Attach the negative jumper cable lead to the bikes frame

Then put the positive lead directly on the starter motor contact (where the wire from the battery/solenoid attaches to it) This will cause the starter to spin. Don't keep it connected for to long though, and watch out for sparks.

If you still have the same problem after doing this you can rule out the battery and the solenoid being the problem.

In case you miss it, like Easy Rider says below me, make sure the bike is not in gear when you do this.

CAUTION: Make sure the bike is NOT in gear. This proceedure bypasses all of the safety's and may cause the bike to move forward if it is in gear.........causing damage and/or personal injury.

Thank you guys and I will definitely make sure it is in Neutral when trying that. Would hate to lose a pinky toe like that.lol

[filson445]

Okay I connected the cables and hear the starter spinning. Still have the same problem. How do I check the starter clutch or should I have it done at a shop?

If you need to ask the first question, then the answer to the second one is: YES! (if you can find a shop that will work on it).

[Aussie Steve]

ER is right in one respect if you are not mechanicaly minded...I tend to take the other view that nothing ventured nothing gained...of course this can always end up with a pile of bits that you have no idea how to re assemble!!!! If you have access to a manual then you're laughing...........or not!

Sorry...not as much help as you probably expected but most starter clutches need special tools to lock them in position (if bike makers are to be believed) and there are several different methods of construction and dis assembly techniques just to make things interesting.

my guess is the rectifier may be shot if its draining the battery overnight. rectifiers job is to convert ac from the alternator to dc for the battery. now if the rectifier is shot then the diodes in it will either fail totally (the battery will have charging issues) or it will fail open and allow electricity to go both directions through it, which is bad for the bike electrics when its running and bad for the battery when its off as it will allow the electricity to travel the wrong way through and to discharge the battery.

some bikes have the regulator/rectifier as a single unit (more common the newer the bike) or seperate units (not likely given the age of the bike you've got).
