Just about to purchase some goodies for the XR650R, and figured it was time to break down and get a desert tank (been too broke until now). Anyway, I could be wrong, but I remember seeing various posts in regards to all 3 tank manufacturers (IMS, Clarke, and Acerbis) about problems with rubbing on the XR650R (be it the radiator hose, valve top, or other). So, does anyone have any conclusive information? I'm looking for a ~4Gal tank, but can go down to 3Gal if that is the only way to stop rubbing. Thanks for the help! PS - Also, has anyone tried Fastway F4 footpegs on their pig (if they even make them)? I have them on my CRF, and like them quite a bit.
