Speedfight 2 makes a lot of noise when stationary, clunking!

Hi, Just bought a cheap speedfight2 to add to my collection lol

Anyways, it makes a lot of weird noises when it is stationary, had a quick browse and a few people mentioned this happened to them when they started it first thing in the morning, however mine seems to make this noise every time i stop the bike and the engine is running i.e. as in when the bike is on and I am not throttling at all.

It makes a clunking/grinding noise which is quite worrying, but it seems to go away when u throttle.
what could this possibly be??

Thankss!!!

 

i reckon it's idling too low

when mine was idling low it was really clunky and sounded nasty...but put the idle up a tad and it goes away.
try it

 

sounds transmission related.
