The bike was finally ready to ride. It did have a bit of a weep from the cam tunnel o-ring...
First ride out and it was badly leaking from there by the time I got home.
So, I decided I'd get the head off to replace the o-ring;
The two inner, front head nuts were not very tight and felt funny when taking them off.
Anyway, once the head was off I found that the two inner, front studs were about 7mm lower into the cases than they should be and the threads were stripped. This is because there was only about 2 threads worth of stud available for the nut to screw onto.
The whole of the the o-ring groove was full of blue sealant.
So I have pushed the bike into the back of the basement until I can bothered to get those two studs out and replace them..
