Replacement master cylinder for GS1100?

[selecw]

Anyone know where I can get one - either OEM or after market?

My bike is an 82 1100EZ.

Thanks

I don't think Suzuki sells a complete master cylinder anymore. Parts are available though so you can do a rebuild as long as the bore is clean. Dual disc masters are typically 16mm but I'm not sure about your bike in particular. I think that any master with the proper diameter will work - you may have to crimp a wire or two to get the brake light hooked up though.

Thanks. When you mention 16mm diameter, what component are you taking about?

As long as it is for a dual disc and the brake line and bolt is the same size it will work.
Here is an aftermarket one.

16mm is the inner diameter of the piston bore. 16mm is stock of a 550 with dual discs - not sure about your 1100.

If you go with a 14mm bore master cylinder the lever will have a more spongy feel but you will have reduced lever force for any given amount of braking force. 16mm will have a firmer lever feel but you will have to squeeze harder. Again, not sure what the stock size is so you need to do some research.
