PMR
Adjustable Motor Mount

$39.95


The PMR Motor Mount Plate was designed by us as an easy fool proof
way to mount larger 4-7 HP engines in a Baja ,
Motovox or many other style Mini Bikes.
The mount allows for left to right engine adjustment for precise sprocket
alignment. as well as front to rear adjustments for chain tension. 
This  plate solves the problem of having to drill and slot new mount holes in the 
exact location to achive proper chain alignment. 
This Mount system works with engines that have
the industry standard 6 3/8"  by  3" inch mount spacing .
Such as the Honda GX 120-200 series, Honda 6.5 Clones. HF Predator 212,
Briggs, Tec' , Subaru  and other brands in 4-7hp HP  range.
 For Mini  Bike Drag Racers's  it has been proven capable of
handling built engines producing 15-30hp.
