Aoa,
I have 163ML engine. It's water cooled at the moment. I want to convert it to air cooled. I m of the view that replacing only head and cylinder and removing water impeller and shaft will do the job. Any bush can made to shut the holes of the impeller shaft to avoid engine oil coming to the compartment used for water pump.

Since it's 163ML stock is Chinese nomenclature for water cooled single cylinder 63mm bore engine. And it's equivalent air cooled sibling is 163FML.
So head cylinder swap from it will do the job.


Description of the water cooled engine in question is given at below link.

Is it doable?

Anyone done it?
