i had a old set off a ninja, i work in a machine shop-soi tried to convert it all myself and a guy that workd here.. they work but in hindsight - it would of been MUCH MUCH cheaper for me to buy a kit from AWK..
I have one - i took off my 2001 balster. I bought a new set of brake pads to - but decided to go DISK CONVERSION.. i have them on ebay now - my ebay seller id is the same as my name here.
