Question about Hyosung GT 650 Motorcycles
Hi. I have purchased 2005 Hyosung GT650r as a wreck for a project. After 8 months of replacing most bits the bike runs fine until it gets to 5500 rpm. At this point it coughs and splutters and will rev no further. I thought the low cost elimination process would fix this so: I replaced the spark plugs. No good. I replaced the coils, leads and plug cap. No good. I replaced the CDI unit. No good. I upgraded the main and slow jets along with checking the float level. No good. The bike seems to be well made except for the frame paint job and parts are one third the cost of my Suzuki VX800. So I believe it's worth finding this one glitch which I'm sure others are pulling hair over as well. All parts were replaced with factory new. Your ideas are most welcome.

SOURCE: my keeway wont start
Check the fuses. Is the kill switch on or shorting out? Disconnect it and then check for spark. Sidestand/centerstand should be up, Got a good battery?
I am unfamiliar with your Keeway and just trying to help. Don't give me a bad rating if I miss the mark on this one. Thanks.

i had a similar problem on a suzuki gs250t custom, my bike would not start some times and if did start, would run erratically, and cut out, this was after i changed the spark plugs, found out that the supplier gave me the incorrect graded plugs.

Sounds like water in the gas.
ALWAYS have a fire extinguisher on hand when working on carburetors.
For each carb > Drain the carburetor. There should be a screw on the lower side or bottom of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.
Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Put the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.
Please rate this solution. Thanks!

1ST of all i think you should take your bike to another dealer to get it fixed as they should be able / confident mechanics to repair any problem.
But anyway have you checked the throttle position sensor ? of the fuel injector connections ?
just that water could of coroded the connectors.
