Hey there, My XR650R runs as strong as ever, but I did a few changes this past winter. I opened up the side airbox cover. I also have a uni filter/W/no backfire screen, All uncorking upgrades with the honda racing baffle too. Im running 68s pilot, screw 3.25 turns out, b3 needle, 3rd notch (runs better than 4th notch), and 182mj. 0-1000" elevation. Just a bit lean on the bottom, hanging idle, popping on decel (more than before I made more air available) Long story yes, but you guys may have other suggestions before replacing the pilot (prob not though) Anyone have the part number for a 70s pilot jet? I know 3.25 is too much on the screw, and it wants more. 70s would work better yes? Thanks a bunch for any honest input.
