If your going to reuse the housing, reservoir, etc and just rebuild the master cylinder you can get a rebuild kit from the partsnmore website at

https://www.partsnmore.com/cat_index.ph ... ry=chassis

I picked up one for my 81 CB650C, works great! I also picked up the chrome reservoir cap,

I would dismantle your old master cylinder and compare it to pictures of the rebuild kit you buy to ensure that it has all the same parts before purchasing one though.

old master housing is cracked so i cant just rebuild it. i hate to buy one on ebay and have to rebuild it and cost more than a new one. i just picked up a new master for my 1980 yamaha for $80 and was hoping there was a replacement for the hondas in the same price range.

I picked up a new mc reservoir for my 79. I will check to see where I got it. It was not cheap, around $70. FYI, you will need to rebuild the plunger mechanism as well because they are usually dirty and a source of air leaks. I do recall seeing where you could buy the whole set up including the brake lever and the price difference was not much. Let me look at my receipts and get back to you.

CW32-8043K It claims to fit th 79 and 80 and 1980 C models. It was exactly the same as the one on my bike.

It looks like the model CW32-8047K below that fits 81 and 82 650's.

The 81/82 standard models should be the same a the 79/80 as only the custom and nitehawk went to the dual disks.
