Ok I've got a 1998 flh. Last winter after sitting outside work in 20 deg temps I just about couldn't get the bike to start so that discouraged me from rideing a lot last winter. I want to avoid that this year. The battery is only 2 years old now, but when it gets good and cold it sure acted like it was strugeling to turn the enging over. So my question is, is their a good trick to extream cold weather starting?

 

Try keeping a battery tender on the battery at night. What grade of oil are You using? At 20deg temps, You should be using 10W40. Hope this helps.

 

Yeah make sure your batt is well charged. How long is your ride to/from work? Some people's rides are so short the battery on a m/c will not have time to charge back up again. If done daily this drains the battey down over time. A charger overnite should help if you've got a relatively short commute.

 

Thanks guys, I've been running the amsoil 20/50, so I guess I can lower that a bit and even though I do ride everyday a battery tender may not be such a bad idea in the winter.

 

A good battery tender is always a good idea regardless of weather..

Battery tender year round if you want to get the most longevity out of your battery.
If you ain't ridin' it. Plug it in.

 

I almost forgot about winter. Time to break out the long sleeve tshirts. I use a tender on mine from time to time even down south. If I lived up north I would plug in everyday in the winter.

 

Snowed here in the mt. Battery tender and if it's that cold don't ride.
