2008 GT250r misses at 5500. How do I sort it?

[2fellas]

yea its a great bike i have had no probs with it other than a miss at around 5500rpm i heard there is a wire you can cut on the CDI is this true and can any one help me sort it :2guns:

2008? Surely it's still under warranty? Get the dealer to sort it.

[T.W.R]

It's a warranty issue, don't go fiddling with anything just take it back to the dealer you brought it from.

There's a variety of things that could be the cause, but we had one brought from us that was doing exactly what your mentioning but it would only come apparent after 15-20kms of riding and was a fuel/carb fault. All fixed under warranty.

Warranty. Don't mess with it. See the dealer. They don't like you to 'fuck it up'.
And I don't normally swear.

Don't mess with it!!!

You will find the answer on the 250 forum on Korider:

It's the CDI unit retarding the timing to pass Euro 3 emissions standards.
There's plenty of info on here about it, just search.

Regardless of it being an easy mod or not - if the bike is under warranty going cutting wires COULD void any warrranty claims you need to make later on.

Get it sorted properly - take it to the dealer and let them do it.

Else do the mod at your own risk and take your chances.

Hey, 2fellas, welcome to the forum and congrats on getting a Hyo... as noted below get the dealer to do the CDI mod - its a known mod and they shouldnt charge you for it... Cheers DJ

You don't need to cut wires. Use a jewelers screwdriver or a sliver of wood to release the pin from the housing, and just slide it out and tape it back securely.

I could go pull the seat off and untape it and tell you which wire, but it would be quicker for him to google it. ;)

just go back to the dealer and let them google it. if you f**k it your warranty is down the crapper

Just get it sorted when you get the bike serviced. Saves a special trip and is potentially less expensive as they are working on the bike anyway (tho is likely to be free in either case)

hey all thanks for all your advise i unpluged the wire from the CDI did it properly and no more missing engine seems way smoother i also drilled 5 10mm holes in baffel plate luckly my mate ha a real long drill bit and it has a way nicer sound now ...once again thanks ..i love myu hyobag its awesome :Punk:

[Hadley]

So was the engine actually missing, or was it just suffering from the usual hyosung "flat spot" problem?
Mine hade the flat spot thing untill I removed the wire.
It now accelerates constantly and smoothly throughout the rev range, but will still sometimes miss at around 6000rpm.
Anyone else got a similar issue?

[2fellas]

yea was the hyosung special after market missha ha ha ...i pulled the wire out as i found in the previous posts and sheis all good now the exhaust sounds way better as well ...:third:

[Mr. Rock]

i still need to get around to pulling that wire out.. i liked reading about all the people who couldnt pull 1 single cable out of a loom.. hahaha!:laugh:
