Hi Freebird, I might be able to help you with this as I have a rear wheel hub. It differs from most Z1 hubs in that the holes for securing the cush drive rubbers are in the middle of the 6 sections rather than on one side. Apparently, these were fitted to H2s and some Z1s and I've seen pictures of t...

Hi Glenn,
The only time I experienced a problem identical to what you describe was when I tried using a single disk master cylinder which has a 9/16" piston with a twin caliper set up. Twin disks need a 5/8" master cylinder. Is this what you bought?

Having recently re-built my Z1B forks, I think you've got it right.

I have an H2 hub which is dimensionally identical to a Z1 if you're struggling to find one.

I have this master cylinder which I was told many years ago came from a Z1R. Please take a close look at the photos and confirm if it is of interest.

I'm guessing here but I think it's a crude alarm device. The aluminium cylindrical device in picture 1 could be a mercury switch or similar to detect movement of the bike. Are you brave enough to disconnect it all? :-)

I have a Z1B cylinder barrel bored to 72mm that would suit these pistons if anyone is interested. It has had oversize liners fitted so would accommodate 73mm pistons. No broken fins.

Hi Jacko,

I have a set for a Z1B which looks dimensionally the same as your Z1000A. They will need rechroming and I can send photos if you're interested.

Does anyone have a Z1 rear wheel (drum brake) they are willing to sell? Actually, I only need the hub so damaged rims, spokes etc. are OK. I hope someone has one hiding in their shed. Paul
