One too many parts?????

Mystery here, took my KZ 900 A4 apart in 1999 and am just now wrapping up the reassembly. Lots of new everything, my business kept me too busy and a couple other bikes. Anyway, I cannot find this part in my Parts Book or any of three shop manuals, including the factory manual. I know it came off the bike, and at the risk of being a complete geek, I've decided to ask. Anyone have a name/part number for this "master cylinder" and fluid cup? :pinch:

that part not for 900 A4 ????????????????????

pretty sure its to a Z1r

master cylinder # 43015-1041

the cup or reservoir is anyone's guess

+1, After market M/C. Or used from another bike. The reservoir is attached to the master cylinder body / bore on an KZ900 A4. I think the best option is to get a new eBay M/C so you won't have to worry about rebuilding it and a lot even come with a spare rebuild kit. I bought one for $29.00 shipped and works great. Cheaper than buying a rebuild kit for an original KZ900 M/C.


Here is a picture of an original M/C: drive.google.com/file/d/0BxeuyU_DUv0iXzY...SHM/edit?usp=sharing

Here is what I replaced it with:

Looks like an 80 1000 ltd style rear master cylinder to me anyway.

Was your bike converted to a rear disc brake? The remote reservoir looks like it's what's used on a rear MC.
