Pull start install guide for Motobecane AV-7 motor
Yet another install guide for one of the great American made pull start kits available from Treatland
It's always a good idea to do one of these pictorials to help put the buyers mind at ease. This kit install is fire and forget
with no special tools needed. Constructed of 18 gauge steel they look and work great. Get the kit here treats pull start for AV7
These kits now come with either a right hand or left hand threaded crank nut so you can order for either the right or left hand cranks. You must also have the affordable Le Partie CDI ignition installed on your motor.
Here are all the components that come in the kit. Don't worry if these components don't match the Treats
catalogue picture. The kits have been developed and improved so that they fit and clear the other motor parts.
I can only assume that you are installing this kit on your running bike and can say that you don't need to fully remove your stator plate or flywheel. You can just loosen the stator plate so that it will rock out a little so that it will be easier to install the lower mounting block. You will need to fully remove the crankshaft nut as it will be replaced by the one in the kit. I was loaned this motor and crank to use as a jig/holder for when I was building these kits. You will be bolting the pull start cover to the two bolts circled in red so you can now use your 11mm or 7/16 wrenches to loosen them now.
With the two bolts loosened, go to the kits goodie bag and bring over the aluminum mounting block. You will see that the block has two threaded holes in it. The larger M7 hole will act as the new nut for securing the lower case bolt.
Hold the block in position over the bolt and finger thread the two till it is just hand tight. you will want to let the block pivot later in the install
Switch to the other case stud and thread that block as well. Quick note, make sure your case stud has enough
threads to completely pass through the thickness of the block. If not go get some longer ones.
Next you will want to install your La Partie flywheel and set your timing using what ever method you freaky Moby
lovers use. Lay on the starting pawl and then thread on the provided crank nut and special hardened washer. You
can probably see that I have coated the threads of the crank nut with anti seize as this nut will be turned with
considerable force. This coating will protect the threads of both the crank and the nut from galling as the threads slide
past one another. It will allow you to get the nut really tight too.
Use 11/16 socket.
Be sure to install the winding unit onto the body using the three nuts and allans. You can now lower the pullstart body down onto the case. Position the welded seam of the pullstart body so that it will point down towards the bottom of the motor. At this time do not force the body onto the lip of the stator plate. You will want the body to just rest on the lip of the stator plate till after you mock up your two bolts and spacers in case you need to rotate the body slightly.
After you have mocked up the bolts and spacers your can then force the body down onto the stator plate. It is a precision fit so you may have to press hard.
The little rope spooling component included in this kit seems pretty robust but I recommend that you not pull the rope all the way to the end of the spool as the spool is plastic and if you live in cold climate I imagine it might snap the rope or the plastic spool. I have found that short quick snapping jerks work best and really get the motor Spinning for a smooth start. If your rope should break, here is a link to easily repairing the spooling unit.

Starting with the lower mounting block side. Insert the spacer between the body tab and the mounting
block. Thread the M6 bolt through the body tab and swivel the loose mounting block till you can finger thread the
bolt into the block. Wrench it moderately tight.
Now you can jump back to the other side, pivot the mounting block into position so that you can mock up the
bolt and spacer.
Now with all of the blocks,spacers and bolts in position you can tighten all 4 bolts for good
Thats it!! This pull start is very well made and designed and will last forever. I recommend painting over the primer.
