Hi Everyone, thanks for the replies? I think i Know why they have given up. I fitted them as per the instructions! on the instructions that i got with the set it tells you to fit a washer between the adjuster and the swingarm!(why i dont know). this washer causes a 1.3mm gap between the guidance and the swingarm. this gap is what has allowed the movement in the system. Thus causing the failure of the alloy. I have took lots of photo's and made a powerpoint presentation and sent it to gilles as i am sure the instructions that i revieved for the 06, 10r are wrong. i bought them for my brother for his zx6r and his has no washer uls8,4 fitted. I know that this is a long one guys, to everyone that has them fitted is there a washer ULS8,4 fitted and if so wear do the instructions say it goes. if anyone wants to see all the picks i can e-mail them. many thanks for the help guys oh ment to say yes i tourqed the spindle up!
