I've done about 4000km on my 2012 GT250R and in the last ride or two it has started rattling when I'm on the throttle at around 4,500-5000rpm. If i pull the clutch in but keep accelerating the noise continues.
Any suggestions on where to look first before I consider taking it to a professional?

So problem was found. Even though it wasn`t what anyone thought.

Turned out the problem was something simple bike needed oil. (Not sure where the oil went.)
Put in 2.5 liters of oil and it cranked better. Checked and both plugs were dead. Replaced them and bike started fine. Set the idling down a lot and its running good, just still sputtering a bit at 5000rpm and up in 3rd gear and higher. Might just be a bit of dirt somewhere, will check the bike over the next few days and update.

Edit.

Changed the front plug, was a bit of a mission doing it.

Plugged looked similar to the other one, maybe a bit blacker though.

Bike didn't start.

Attempted to use the starter spray, sprayed it twice, sounded like it was trying to fire.

Sprayed it twice again, it fired once then died off.

Didn't spray it again, but this is the audio for the last attempt.

Bike is on the charger at the moment to make sure its charged before trying again.

How many sprays should I be doing max ? I read that you should only do one-two for each attempt?

Didn't want to over do it as you expressed the danger of it back firing.

*Edit 2*
Tried to use the jumper leads from the car as well. But it didn't change anything.

It seemed to work better when i took the air filter out, sprayed it in, put it back on and then started.

To replace the front plug, you need to shift your focus up a bit. The plug goes through the top of the cylinder head. Do not remove your exhaust. By top of the cylinder head, looking at the picture you provided, you can see the top surface just starting to come into view.

Argh yea, I should have noticed that :/

Using a start spray doesn't fix anything, it will just help to start a flooded engine and the combustion would eventually burn off the excess.

It helps start a flooded engine because of its low ignition temperature?

The spark plug image you provided does not appear to be wet. See the part that hooks over? That's the anode. The bottom surface of that is a perfect 'light tan' colour. This is ideal. If it was black, then you would suspect a flooded engine. if it was clean/white, then you have a 'lean' engine, which means the air:fuel ratio has not enough fuel. See my notes in the previous post regarding why it should be a wet plug. This is not what I would have been expecting.

Screwing the plug in and then taking it out will not give any indication of conditions inside the combustion chamber. The spark plug would have needed to be in there while you were attempting to start the engine.

Will try to start it and see what the condition of the plug is.

The picture you provided is indeed of an airbox. Unfortunately with EFI bikes, it's not easy to raise the fuel tank and yet still keep it connected. Otherwise, yes. That is the right place to spray.

Yea, noticed that when I took it off the first time.

You would not have time to DO anything. If you have a fire extinguisher, keep it handy.

If I don't reply with a update. Rip me.

Ah, Yip

Thank you for your reply back,

yes i am not to sure about if its illegal or not, be honest i normally clean my pipe once a month and take the bike out for a ride without the muffler.... (sound so awesome!) =D been pass alot of police they didn't do anything, for New Zealand the police system is werid, some times they care, sometimes they don't its werid... the sellers got two different styles for this piple

style one  clamps on the exhaust sides over the header pipe,
style two  clamps on the exhaust sildes into the header pipe

only other option i was thinking is style two, but it would look pretty ugly with the big bracket lol...

oh well, sounds like i thing not to be =(

(editing) i think i might try this pipe just looking at my Maximum Noise Level Legal limits for our motorcycles its 100DB if greater than 125cc if less its 96.....
thats **** loud! \o/ might be able to get away with it seen the ebay pipe is 105


You understand the problems.

There is no simple solution, unless you cut your header, you cannot fit a 'slip on'.

Every Hyosung is like this. Even the "gtr650s", what ever that is. ALL Hyosungs have a flange.

That exhaust would be very very very loud. No difference with no exhaust at all. If this is illegal where you are, the Police can pull you over and fine you.



Looked into it and it seems the limit is 100 it seems as you said.

http://www.nzta.govt.nz/resources/rules/vehicle-equipment-amendment-2007.html

I also live in NZ and agree that the police have a wide range of different attitudes. I would say that it would depend where you ride, if you ride in cities or towns then I can see them pulling you over. If you ride it in more rural areas then I dont think they will.

Hope this helps.

17mm is not correct, they're quoting the manual.

My floats were roughly at 10mm each and gave me all sorts of problems, setting them at 7mm sorted everything.

7mm is the correct float height.

Going to an independent garage may help, just make sure that they understand that the correct float height is 7mm, that the manual is wrong and there's plenty of sources on the internet to support this.

today i call 2 different hyosung dealers and ask for the check for my float height,
every 2 say: the 17mm is correct and there is maybe another problem on my bike !?

i think is better i go to a "universal" garage with NO hyosung in stock :p
