I've been using 2008 R6 usd forks on my Yamaha Fz6 for several years. Recently I hear some strange noises coming from inside the forks like squake while low speed riding on bumps. So I'm planning to service forks soon. I thought if I can buy a new set of upgraded oem fork internals, it may be better. They are sold for around $100 on ebay as new. What do you think, do they fit?
