    Have you adjusted the clutch? They are not adjusted correctly straight out of the box.. And that's not the half of it. Read all the newbie threads stickied in the forums.

    I have no experience myself with these things but from what I've read it might be an air leak somewhere. (probably in the carb, but as I have said I have little knowledge on these things)

    It might be normal.... Have you ever drove a clutch before?

    I think Frankfort means a manual clutch as opposed to a centrifugal clutch..
    We have a whole section on the clutch and problems with it but first step is adjustment. The kit arrives out if the box with the clutch inoperable. The flower nut is the key here.. Best to use the search function (top right corner ^^^) to save typing it all out again.

  7. You have an air leak in your intake manifold from your carburetor check it out. I would bet just about anything you haven't really because the same thing happened to me. When you assembled your carburetor there is a little line in the barrel, Fat lion in the barrel has the line up with the little tiny nose inside of the barrel where the barrel goes into otherwise the barrel won't go all the way down
  8. When you put your car together was it really really hard to get that spring pushdown If it was a guarantee that your problem you don't have that line in the girls lined up with the knot inside of the car where the barrel goes in When people tell you how to assemble your card they never ever ever mention the little knob inside the carburetor that has to line up with the barrel. If it doesn't line up the barrel doesn't go all the way down and it's constantly at Full Throttle. That happened the very first time I started my bike . Please please please check that first Good luck to you

    I think it's mainly a user error.... It took me a while to get used to riding a Motorbike (aka MB)
  10. Clutch pedaling etc?

    probably just the slide stop screw in too much, keeping the throttle partly open.

    Did you try holy water? Sometimes things that are possessed by demons will operate or move on their own.

    Sorry but I had to say it, he left me no choice...
