Alrite mate,
could be the timing chain tensioner,check that first. Ive had mine go on me RX125 with a costly rebuild and my brother had his go on the GTR but stopped riding it just in time. That would be my first port of call defo

hope this helps

its seems to happen wen you rev it a bit and then like i say its fine after a few mins. i took it in wot you said and gave my local dealer a ring and explained wot was happening and asked if it was possibly the cam chain tensioner. In his words he said that a few years ago there was a recall on hyosung bikes due to the cam chain tensioner they ad to be replaced. i brought my gt125r back in nov2009 brand new but the bike was manufactured back in dec 2008, i dont no the date wen they where recalled if anyone know that imformation please say. The Chap also said if it is the cam chain tensioner it would make a lashing sound and the sound would be constant  rather than a tinking sound that dies of after 2mins of been started (only wen u rev) but he stated it could be possibly sticking and he said it could be a spark plug or cap are on the way out or it could be exhaust manifold blowing. im gonna try changing spark plugs over to elimate and check front mainfold.

when you brought your bike did you get the warenty slip ring them up they have a list of chassis numbers i had mine replaced but mine has just gone big time now the chain has come off the cam shaft (rear cylinder) knobheads at culwins motorcycles quoted me £2500 but i think he wanted to sell me another bike and as my bike is 4months out of warenty i've got to do it myself.
