Ok guys finally back to riding blue again...loved that XR650R but just too damn heavy for me. Previous owner didnt give me much information so not sure if he did all the work himself or not. He did say he had NOT cut the grey wire but I'm noticing what looks like AIS eliminated and something else removed (blue boot in picture) as well as cut the air box. It seems jetted well and runs like a bat out of hell even with the sparky in the exhaust which I just removed. What do you guys think? Do those snorkels need to be removed? What is this blue thing covering? Valve cover coming off next to check those after she's good and cleaned...dirty as hell when I brought her home.
