Strange engine noise

    Got my motorized bike kit a few months ago, it is a silver 80cc from The engine makes a funny noise like if you said "wobblewobblewobble" really fast. The noise happens at all throttle positions, and when the clutch is both in and out. I know for sure it is an issue with the engine because i traded just the engine with my freind and he now has the same problem. If the clutch lever is pulled in, the noise only happens if the wheel is at a certain orientation, and once it is rotated a few inches, it stops. But then when the wheel goes back to that spot , i her the noise again for a little bit until the wheel moves past it. This makes it so that when i am riding, the noise is constantly off and on, and it is very annoying. I tried look ing in the gear case for anything out of the regular, nothing.

    Can anyone help? Thanks.
