2000 Ultra - I commute on my Harley and it is difficult to start when it gets under 20 degrees. It almost wears the battery down trying to start the bike. Otherwise, it runs great. Does anyone have any tricks for cold weather starts?
As HD_noobie said, it's all about the battery. Temps in my region range between 0°F to 120°F so batteries only last me a year. When they start getting weak (usually when the temps start dropping hard), I order a new one and carry a Lithium jump pack until it's installed.
Make sure your ground near the starter and the transmission housing is free of corrosion, that's a common spot for power loss. If the bike has high miles, it might be worth checking power output from the regulator also.
This is a good battery.

Put a torpedo heater on it for 10 minutes. But the problem is you need to get home.
Amazing how heat helps things start.
They make magnetic heaters that go on oil pan. Not expensive, you could try it. Just stick it on and plug extension cord in. Though not sure if pan is steel.
For my diesel tractor I let a torpedo run. Have used it on 4 wheelers.
Milk house heater might work if you let run half hour, play with how long.

Torpedo heaters put out a lot of moisture, use them on construction site or in a barn, not a garage where corrosion prone parts, tools etc. are stored.
Hang an old style trouble light next to the cylinders.
