Engine Trouble First Bike/Motor - Low-power and runs rough

[motorpsycho]

sounds like the clutch is toast or way out of adjustment.
I'm not sure how to go about adjusting a centrifugal clutch and it may not even be possible to adjust one...I have no idea.

So what was the vibration issue, and the fix.

 

[HeadSmess]

it could be the clutch, depending what brand it is...if its maxtorque, definitely! i had one of them die within a week!

lets seeee, it vibrated like mad, then smoothed out at certain times, seemed to be a matter of luck. things that arent lined up well and spin at 6000rpm tend to vibrate badly.

it always drove though

you still didnt say if its friction drive or chain drive or give us a pic so....

im going!

(it could just be one of the clutch shoes has spat its lining and there goes the balance...and the drive...what sort of noises is it making?)

I have a 49cc motorized bike and when I was riding it yesterday it just lost power and sounded like it was bogging out and then the clutch cable snapped what could be the issue?
