Hi
Couple of thoughts ,
Did you check the engine mounting in the picture? It really looks knackered and possibly separated/ sheared , new ones would help align the exhaust and give a much better drive.
I would use a thicker oil , 20/50 will suit it better , the modern thin oils are not really suited to a old school motor
Also they will run for a good few years with fair bit of engine wear , so unless its going to be your daily driver ,just keep enjoying it,
Simple engine to rebuild , but parts cost over there might be wallet damaging,
