Starters ...

Well ... Sunday Morning , 30 October .

I  have now to Know WHAT IS the Exact Lenght ( Axle to Axle ) 

between the Rear Chain Gearbox's Sprocket and Wheel's Sprocket .

I don't want to be obliged to add a rear Chain Tensioner to this Scoot .
( IMHO : i think that is Ugly and smellin' kinda "Last-Chance-Option"
and Most of the Times : these "Skate-Board Wheel" Type Mechanisms works very Bad . )

In my very-last Post ; i said " it is the Rear Chain Which decides of this Lenght"

So , Now : let's take a Good Range of Measurements about this .

23 Teeth at the GearBox and 44 at the Rear Wheel .

( I know : that is an uncommon Ratio , but this is Guy's Exact ShovelHead Sprockets Ratio ...

and it work FINE like that ! )
