I decided since I've got the subframe apart, to go ahead and delete the rear brake reservoir. Before you freak out, let me point out the stock reservoirs hold way more fluid than you need. Also they are just God awful to look at on my bike if you don't have rear pegs like me. So what I did was I bought clear Tygon 2075 tubing off a chemical supplier's web site, you need Tygon because brake fluid is some really nasty stuff that will eat thru plastic tubing. Then I simply took off the reservoir from the rear master cylinder, and stuck this on it. The race bikes use this for weight reduction and simplicity. I just did it because it was convenient, unique, and fixes my problem of my subframe looking like a pot rack. I later took a grinder and shaved all brackets off the subframe. I'm fashioning a cap for the Tygon Tuesday out of a hex head bolt, gotta cut the threads off it and I'm done.
