random squeeling for few seconds when accerating

well when i accerate pretty fast but in a smooth manor there is a slight squeeling noise sorry bout spelling which only last bout 3-4 seconds then goes i thought it could be my electric water pump but could it also be my oil pump on the way out or would it not do tht?

 

Does it jerk off the line sometimes too? Coz on my runner when its cold the first few times I pull off, the bike just jerks off the line and makes a squeek for a split second but the variator is trash, so it could be what minor said and the variator could be shagged like mine.

 

might just be a worn belt
