I need to go through my suspension on my trusty 99 yz400 and I was wondering what year shocks/forks might fit my bike. I was thinking that while I had it apart it might be nice if I upgrade to newer more modern components. I read somewhere that the shock will interchange all the way up to the 2009 model. I am not sure about what forks might swap out. If anybody knows the answer to this I would greatly appreciate it. Thanks!
