It doesn't matter how good the seals are or how often you change them, the design is seriously flawed and will not work consistantly. Best option is to ditch the vacuum hubs and buy manuals instead.

On that subject......I am about to put the manuals on my Sporty and all the instructions(???) refer to the placement of the vacuum feed items in the US model (photos not real clear on what is what). My question is what am I looking for in terms of shape/size/likely position for vacuum servo, tank, and the connector that needs to be disconnected?
