I got my good friend hooked up with a low hour 2002 YZ250. I'm unfamiliar with YZ's, but I know the platform is tried and true with many die hard Yamaha/YZ enthusiasts out there. So I was hoping perhaps there are some great websites, write ups, blogs etc for things like parts cross reference / compatibility, tuning and other general tips and tricks. Something like a YZ owners bible of sorts. Thanks in advance for the help!
