Need help Identifying MC

[Sci85]

Hey guys,

Was planning on finishing up the brakes on my 82 550 Katana rebuild this weekend so I ordered rebuild kits for the front and rear master cylinders. Unfortunately the front rebuild kit does not look anything like what came out of my front MC even though the part number is correct. So, it must be that someone used a different year MC on this bike at some point. Can someone help me identify what year this MC might be from?

the pic below is what was on the bike. The lower spring, piston and cup is from the correct year rebuild kit just for reference.

Thanks,
Sci85



Just the piston assembly from the installed MC that I need to identify.

It doesn't look like either Suzuki or Yamaha part to me.
Perhaps from a Kawasaki?

Beats the heck out of me. I've been perusing ebay but can't find a katana one. However, I did find some GS1100 MC's for $50.00. Seems reasonable to me. You think that would work ok? Here's a link to the offering...

That one should work and will probably take a while to get to you.
Great price for new.
