I posted several weeks ago that my motor trike wasn't level in the rear. It ended up being out of level about an inch. Following the service manual I adjusted the trike to within 1/4 inch. For the first time my rear bottom hatch springs open instead of me having to dig at the top of it to pull it open. I wouldn't have thought such a small amount off level would have an effect but the hatch proves something was binding.
