[QUOTE="Len Matthews, post: 14219, member: 178"] A comment if I may concerning sealing the dynamo against the back of the sprocket housing. Oil loss from here is usually due to excess oil in the primary chaincase. It's well known that most Twins have a tendancy for oil to pass through the drive-side main bearings necessitating the need to drain off the surplus via the level screw.If you seal the dynamo in the way some have described you will prevent the primary chaincase from breathing so any pressure build up will be forced into the dynamo. (Or into the gearbox, won't it Hugo Myatt?!) The felt ring in a Miller dyno won't stop much, far better to use sealed armature bearings which are readily available from bearing stockists. [/QUOTE]
