Yep after fixing the drive shaft output bearings this devil bike now presents me with a head gasket gone on number 3 across the water/oil circut...nice milky coloured oil and a nice splashing of coolant on the back of the valves from the swamped bore (see pics)..1 and 2 perfect and number 3 wet

.....Will update this thread with pics as i go and swap the gasket out. BTW guys anyone have any links to a UK stockist of head gaskets or complete head sets?
