I'm 6'2" 230lbs and looking to make some suspension mods to my 2000 XR650r. Any suggestions? I am an intermediate rider that preferrs resistance to bottoming over plushness in terrain that includes some tight single track and open fireroads, east coast style. I would be interested in a few mild motocross sessions if that wouldn't be too much to ask!?!! Will stock springs handle this type of application? I think I have a couple bottles of 7w fork oil and one 5w. Stock oil level? Shim stack configuration?
