Howdy... The fuel pump in my bike appears to have frozen up during the three years or so that it's been sitting. I'm assuming that the only way to access it is to remove the big triangular frame member that the pump lives behind (which the battery box mounts to)? And if so, any caveats about taking it off? Don't have a service manual and would be grateful for any tips, or if there's a less invasive way I can't see. Thanks much.
