Thanks AVB, attached is an image of what my machine looks like, think it is an L-head. What I'd like to know is how much work I'm up for. Removing the head will mean a new head gasket? Just want to know what supplies I'll need before I start, whether I complete the job is another matter. Have taken 2 strokes apart but never a 4 stroke so not sure how much valves etc complicate things. [Linked Image]
