cool thanks timeeh, I'll grab it tomorrow then before easter.
There is no metal seal thing there and its hard to get hold of one for it. and yes there is a leak as it smokes from around there and is very noisy which I think is noise coming through there as well.
Its coming along now, got most of the wiring done now, got a new battery today, am going to bikelec to sus out a 6v 2 pin regulator and then its just things like control cables, new parts going on, replace the clutch gasket and a lot of waiting for parts to arrive.
Got 3 and a half solid day to work on it next week so there will be some progress.
