on my aerox i can accelerate hard with no problems but when i try a wheelie the bike seems to die and bog also i can hear a cracking noise coming from the tranny at very low speeds aswell as a loud winning noise as i accelerate and hold at 25 or above but at lower speeds their no whistling. and the bike rockets up to 65 no problems its a 70 the belt shows a little bit of fraying about 1cm along the side of the belt. i dont now weather to buy a locking tool to see if its my rollers and find out their fine. oh well i need a belt soon so il buy one once their in stock
has your bike got a gear up cos if it has then it will whistle. crackling noise might be the kickstart rubbing on the cog occasionally i get the same on my bike.
yeah it does thanks for your help i thought their must be somthing wrong with my bike cause i bought it like that.
na gear ups whistle. because theyre straight cut (or so i've been told) check your rollers. and belt for wear mate.
bent clutch plate or somthing up wiht the clutch, its making noise befor the clutch and bell lock together from what you explain
