OK, I have been trying to figure out what is wrong with my 748 for some time now and finally gave up and took it down to GP Motorcycles so they can figure it out. For those of you who don’t know, when I bought the bike the brakes were pulsing. I figured that it was just warped rotors and replaced them and the pads. This cleared the pulsing but created another problem in that the wheel did not want to spin freely. It would turn but you could tell that something was causing the wheel to not spin totally freely. But it stopped just fine so I figured I would take it to the track:

Well, it ran fine but was still binding. A few weeks later I attended another track day but the problem persisted and actually got worse.
It has been at my buddy Kyle’s place for the past few months as we traded all of his parts for mine (he had crashed his 748 at that last track day). We just could not figure it out. We tried replacing everything and finally replaced the axle. Well, that helped a LOT. We got it to spin pretty well but could not get the “squishy-ness” out of the brakes no matter how many times we bled them. We also noted that the left rotor was actually bending when we applied the brake. So, I finally admitted defeat and took it down to get the pros to look at it.
Wish me luck!
