I would like to upgrade the front master cylinder on my 83i. I have unlinked the brakes and feel like I could use more volume. Can any body suggest a later model master cyl?

You could go to a slightly earlier master cylinder since the 80-82 1100s had unlinked brakes.

I was hoping for later model. All of the ones around here need a complete redo including a new reservoir. For the same money, I would like to upgrade. Jay

I don't know the output volume of the different 'Wing models front master cylinders but it would seem the '83 on might be a bit less than the earlier models due to the linked brakes. I suspect the GL1000 front master has the largest output becausethe calipers both used large dual opposing pistons that are larger than later model calipers. Perhaps you could use a master from a bike other than a 'Wing that has unlinked brakes and has a 7/8" diameter handlebar.

I have been thinking about a later model sport bike style master cylinder. I like the look and I think the divorced reservior would be easier to adapt to the handle bar angle. I do not like it when you can not fill the reservior to its limits.
The only real question is how not to over volume or pressure the calipers. Resulting in no lever travel or twitchy brakes.I am not wholly sure that a caliper and rotor upgrade wouldn't
really be useful. I haven't been impressed with the front brakes. I hope that adding a different master cylinder will boost performance. Jay

Check out the Ebay replacement unit. I don't know anything about it except what is listed. The photo shows it mounted on a GL1100. See link below.

What about stainless steel brake lines ?

Broke Winger put one of those on his GL1100, and he loves it.
