Large Rear Master Cup. Where To Find? was created by chopper1963

I'm putting the rear brake master cylinder on my 1981 GPz550. The current cup spigot I have is small, ID/OD whereas the spigot on the rear master is large ID/OD. I need a cup with a large spigot that exits the cup on the bottom left. Can anyone help me to find one or search terms to use on ebay?

TIA

They should make searching more productive.

I'd rather not pay $40 for a plastic oem cup when there are so many cheap ones out there.

Here are the two cups in a pic. I need the LHS one.

That looks very similar to the Yamaha R6 unit I am using on my build, I got the rear sets, mounts, master cylinder and reservoir for $60 on EBay so a reservoir should be cheap

My "master cylinder"

on the Suzuki looks like that. Hell... use a piece of hose!

Don't be ridiculous! It's only a flesh wound!
