I found a new in the crate 2003 XR650R I am buying for cheap at a dealer looking to unload it. What do you guys recommend for break-in prior to mods. Can I uncork immediately? Also the Edlebrok pumpercarb...worth the money. Does it provide more power than a properly jetted unit or just easier starting. If I decide to go to a HRC kit beyond uncorking...should I concork or does that kit provide the parts for both?
