02 GL1800 w/Auto Pilot
If you would put a Battery Tender on every time you get home, the next time you let it sit for 3 weeks, or 3 months, it will start the first time.
you are quite right on the fuel evaporating from the carbs.My 1500 has to be cranked a while if it's been sitting a long time - like a month, not a few days. I try to run bikes fairly often. They really don't like to sit for long periods. I'm not sure why. But when I put a bike back in the shed after a run, I always put marine Stabil in the tank and run it enough to get in in the carbs. On the 1500, I'm guessing the fuel in the carbs evaporates and I have to crank 'til I refill them. I don't know much about women either.
Nope, it's better if the engine starts right away and spins the oil pump faster to get the oil pressure up & sling it around. A turn is a turn on a dry bearing if it's cranking or running doesn't matter.I think there's a benefit to having to crank the engine a bit after a long layup: The bearings might dry up a bit and a crank or two would help lube them up before the start.
