A two-part enginemount allows you to finetune the chains tension without loosening the enginemount from the frame.
Also the enginechange is easier and faster if each engine is equipped with its own engineplate.
The motorplate/upper part of the bracket is made both in flat, and in a angled version and is delivered without holes for the engine. (needs to be drilled)
