I done it to my 02 gsxr1000 and I have brakes NOW! they work much better. the 1000 brakes always felt like they still had air in them, no matter how many time I bled them...I just could never get a good lever fell out of them, even with the braided lines..I'm very picky about my brake lever feel. I put the 750 ones on a bled them, 5 minutes later I had great brake lever feel. Like a rock!
