mts 1200 engine

[/img]my 2011 mts 1200 s has become hard to start from cold, this morning i found coolant around the front cylinder exhaust joint.
i took out the spark plug and shoved a camera down there hopefully i have attached a picture, it is a little damp in there.
it has had its coolant mod

sorry for lack of photo but it turns out the front cylinder has a porous head coolant leaking out the exhaust port.
