Help! Weird sound heard whenever I close throttle

[coldblizzard]

As stated, I hear a weird sound whenever I close throttle at considerably high speeds, and I've never heard it before. It happens all the time now, whenever I move above 60 km/h, and I just close throttle suddenly, the sound is heard. Sounds like a zap from electricity, but I don't know what's wrong

 

Would really appreciate it if any bros can enlighten me. Thanks!

 

PS: Its a NSR 150 SP

could be backfire.....

 

backfire by 2 stroke bike (nsr 150)?!

2 stroke bike can nv backfire like a 4 stroke bike..

due to the way how the petrol and air being drawn by a 2 stroke engine and the rev cycle..

i also experience dis sound, when u close trottle, its sounds like some electric/water squirting sound. haha, have being living with dis sound for quite long liao, nothing seemed wrong.

if trottle is low, no sound, only when u trottle to a level. when stationary also no sound, even if i whack the trottle

 

the sound most likely comes from he trottle cable. but i dunno wad cause it.
