According to BRONZ it's 1 December, but not yet confirmed.

Glad you had a win
Alot of people slag Hyo's out, and in some cases it's justified. (Same as all makes and models).

But they are a reasonable learners bike, that are solid if cared for. Enjoy

Vacume fuel taps had a known fault, and were changed out on alot of GT's under warranty.
Basically, they struggled to supply enough fuel to the carbs over about 15kms, until the fuel level lowered too far, and the bike would stop.
By the time you tried to restart a few times,the fuel level lifted enough, so the bike would retart.
Inaccurate machining of the clearances inside the fuel vacume tapassembly was the fault.Out by about 005".

Frustrating and time expensive to fault find.
Maybe try a manual,(non vacume)tapfrom the wreckers off a similar sized bike.

PS, Scottyand the team at Hyo NZ are good blokes.

had one bike doing this when i was working on hyosung it proved to be a bad connection in the cdi, was bloddy hard to trace as it would never fault when the customer bought it to us. This bike needed to have been running for 10 15 min and then hit a bump to bring on the fault, is this what yours bike is doing? Do you know any one with the same model of bike that you can give your cdi to to test to see if the fault swaps to there bike with your cdi fitted.

I asked the guys at hyosung if they knew anything about the "retard wire" in the cdi, others have taken out the brown wire and had success. However not sure what your meaning about it cutting out?
Hyosung told me "sure go cut the wire then come back and buy a new cdi unit" they suggested having the machanics look at it at $80 an hour until they find it.
Now I only asked about it didn't say i was going to try anything and he almost busted a nut over my query.
Chances are if I tried anything i'd somehow manage to blow up my suburb

Hi mate, checkout the post called Hyosuck posted by KIPS powerband. He was having similar issues and got some relief. I can't remember how to quote one thread into another but it is easy to find

I have done this mod also but it I don't think this is your problem as when the vents blocked the bike slowly stumbles to a stop and then won't start for 5 to 10 minutes.

try wiring out the side stand switch, I use to work on these when working for a hyosung dealership and have seen several faulty swiches. they cut the ingition out for a second when the stand vibrates when hitting a bump. Put a temporary wire link in to the connector up by the tank and take the bike for a ride to test if this is the problem. I would recomend to fit a new switch if it proves to be the problem as taking off down the road with the stand down isn't much fun when the stand digs in.
