I got my brembo yesterday and tried to use the resivior and line off my gsxr1kmaster and the brembo res tube is skinnier than the gsxr one. What options do I have as far as using my old res.? I bought skinnier fuel line but i cant ttry it till i get home. I wish I would ve just got one with the brake, but instead of gettin one with it u gotta pay more for it. $210 and they wont even give you a $2 resivour.
