Just bought a 2017 XR650L I have been riding a CBRRR1000 for the last 10 years and my old body is falling apart(might keep it) my last endure was 1978 yamy xt500thumper.The 650 is a good looking bike but I think the tank will be the first thing to change and I see afew guys added a oil cooler, do you think its needed I never had probs with the old 500
