Fun motor to work on AFTER you learn their ways. Modular design means lots oi joints and
all joints have to seal. The leak may be easier to live with for the present than diving into
for that alone. In any case gaining access to leak will almost certainly cause damage to the
gaskets that do not leak now, but, will if just put back together.
Gasket between water jacket and cylinders, gaskets between water jacket and spark plug
flange, gasket water jacket to water jacket, gasket water inlet tube.
Plus some time and effort.
A full tear down to replace all gaskets and seals may not be on your agenda given that
decals and some parts look good. Leave it be or restore…hard call.
