110cc Shineray/Chinese ATV Engine Whine
 

Hello,
i have a shineray 110cc quad and it is making a brutal noise in 3rd gear. This has only happened when the engine is warmed up and i am going like 10mph. All of a sudden it starts to make this high pitched whine. It seems to be coming from the gear box and i am afraid that my drive shaft or the 3rd gear might give. If anyone has any advice or has experience with these 110cc Chinese ATVs

PLEASE HELP!!!!!!
