I may be wrong, but just getting rid iof the EBC's may not solve the problem...warpped rotors are caused by hot spots, i.e. hard braking before you stop, the rotors heat up where the pads are, especailly HH's...but the rest of the rotor cools off, If before you come to a rest, use the rear brake, and be kight on the front...I had warpped rotors, with EBC's, got new rotors, and followed the above, and never had a problem after that.I'd bet money it's one or both of your rotors. Do you have a buddy with a gixxer that you could swap wheels or rotors to try out?
If you find out it's the rotors - problem fixed. But to keep it from coming back I'd ditch the EBC's. The best pad out there in my opinion are the Vesrah SRJL-17's. Spendy, but worth it. I've heard the standard RJL's are very good as well, but have not tried them.
not necessarily....especially w/o steel lines.Definitely wouldn't be the rotors. If it was the rotors, he'd be feeling a pulsing at the lever, and not the whole front end racheting like it is. Also, light braking would reveal the same symptoms (although less pronounced).
meehan8, I have the same problem with my K4 750. I've had some techs take a look at it and speculate everything from brakes to loose steering head to suspension. My gut instinct is that it is the suspension. I was planning on getting my internals reworked anyway; this just accelerates the need.
i had that same problem and almost shelled out for new rotors. ALMOST. lets analyze first. do you do alot of wheelies, especially in 1st gear where engine braking will slam the front end down? that was my problem. the guy i bought my bike from was a wheelie junkie. to many rough landings can cause the front end to loosen up. below is a diagram and i will explain how to remedy the problem:
1. loosen number 8
2. tighten the bottom number 12 (this is where hard landings from wheelies do damage.) you will need to use a mallet and the tool that makes nails flush in hardwood floors. put the tip between the grooves and hit gently. it will tighten.
3. tighten the top number twelve. number eleven is a washer.
4. now re-tighten number 8.
now take her for a spin. if the problem is less noticable now just follow steps 1-4 again and that should be all it takes.
if the problem is gone, then job well done.
if there is no difference, then sorry to say it, but, then it is probably the rotors.
but like i said, i almost wasted $300.00 so it's worth the try.
JUST DON'T FORGET TO RE-TIGHTEN #8!!!
