Hi  just returned for a run out done about 250KM   on my Dragstar 1100 & noticed a slight oil leak from the front of the engine. Not cleaned the engine & checked exactly where it si coming from but it look like its either the head gasket or from the  plate behind the exhaust front pipe at the front of the engine . My question is is the head gasket prone to leaking ? the bikes only done 33,000 KM ? Answers to ease my fears. Is the head gasket a difficult job to replace on the front head please? anyone help ? hope so cya Bill

HG are not known for failing. It's more likely to be the valve cover O-ring.
