hi guys, i just brought a very nice original
nsr250r sp 1996 repsol #222 of 1000

anyway its all immac, but on idle it kinda makes a ping clin ting bing sound, not very load though, and it goes away when u throttle upto 2-3 k .
only makes it when sitting on idle, kinda sounds similar to clutch sounds (dry but slower and loose sounding)

doesnt effect the bike as its still runs nice and quick as hell!!!.

is this normal? am i to worry? , thanks guys
