@mxbarnhouse: nitrogen charging rear 2000 honda cr500r two stroke dirtbike shock. key tip - always compress the shock rod all the way in before putting in nitrogen, this ensures the most air is out of the system, and you should see the shock rod push outward. next test your shock to ensure it properly works by compressing the rod and ensuring it fully pushes back out. #suspension #shock #dirtbike #honda #cr500
