Default f4i brake master cylinder

So i have a 2004 f4i, and for some reason the previous owner installed a gsx-r master cylinder on it. Now it loses pressure and the lever becomes very spongy. My friend had a 929 master sitting around and gave it to me and was thinking about installing the 929 as a replacement. Or should i just buy the OEM master instead? ANy advice or suggestions would be greatly appreciated. Thanks

GSXR is probably a radial, but they have a recall so no suprise it failed. The 929 one will work, or an oem will work as well. Up to you really.

My first thought too.The re-called Gixxer radial masters are junk.... There's nothing wrong with using different masters to improve feel so long as the bore on the cylinder is close to OEM. Go with whatever you want.

Hey,

Last year the master cylinder on my F4I failed. I picked one up from a 929 and it bolted right up and works like a charm. Only thing is that it blocks the tiny orange shift light on the cluster. As long as that's not an issue for you, I'd go for it.
