That sure sounds like a giant pain in the ass (having to manually operate a gate). I hope that you continue to have no problems. But couldn't you get a power gate operator? I know I'd be looking into one. Can't be much more expensive than a garage door opener.I very commonly have to park my '13 facing downhill to open the gate and enter my property. And then again to close it after I pass. The bike is in gear and (of course) not running in both cases. Many dozens of times and never a problem.
Me... I'll continue to park with the nose of my bike up-hill (or at least on the level) to guarantee those results.
YMMV
