I've had my xr650r for several months now and have really been enjoying it. (an 85 klr6oo was my last DS.. just a bit different than the xr!)I bought the bike with several good mods already done to it- applied tripples with cr high bend bars, t-4 slip on muffler, BD kit, gripper seat, eibach rear spring, uncorked and a few other minor things. I want to put another couple hundred bucks into it but I can't decide... i'm considering a new cam, header, oversize front rotor or maybe a gps unit. To be honest, i'm leaning towards the cam. Seems like a good bang for the buck mod. So, if it were you, what would you do next and why? Thanks in advance.
