I recently bought some black side panels for my 650R and im gona do the venting myself, ive seen the pattern from xr's only and it doesnt seam like its venting the whole panel. I was thinking about useing a 1 to 2 inch holesaw and doing a bunch of holes through the entire side panel, and just putting a wire screen over the inside. Anybody have pics of how they did there venting? and what carb settings they have... I currently run a 175 main 68s, and 3rd needle pos, im thinking about after venting i would go with a 178-180 main, and 4th needle pos.
