One thing I've found out of coincidence has helped me considerbly cut down on wrenching time... Opening the hood! It sounds like a stupid statement but it's sooo easy to use external fuel fill with switches on the outside that opening the hood isn't that common. Then when the day is over, you go home, you're starving, tired, and the ski takes a backseat to life. Then the next day you assume everything is perfect until it all tanks one day. When you're forced to open the hood to turn on/off electrics, fill the tank, and charge the battery, it gives you a bunch of chances to catch that little thing that will cause major issues very soon. Maybe a case bolt fell out, there is a little smoke in the engine bay, the gas tank is leaking, the pipe sizzled when a drop of water fell off your hand, a screw fell out of the ebox, etc. Most require 2 minutes of your time to fix now but next week might require a $30-$100+ part and put you out a weekend or more of riding.
Just think of all the things you could be looking at while you're bored out of your mind filling the gas tank up....Oh look the coupler cover is loose.
