More battery crap. Past few weeks the bike starts real reluctantly first time each day, when it's totally cold. Get click and the starter whirrs. Eventually it catches fires a beat and stops, with whirr. Finally catches. Yesterday had to get jumper cable to start it after running battery down, it was out in the cold (40F) overnight. I was on a trip, usually it's in the garage and on the battery tender. Battery is 2 years old. So, do I need a new battery?

What is your batteries resting (cold, like over night) voltage?

There are a lot of factors that can play into this, but it's a quick check. It's possible that it was low (like you did a bunch of quick rides) when it was put up for the night and the cold over night dropped it a bit more. So it's CCA was not high to begin with.

Personally I put both of my bikes on tenders anytime they are in the garage. (Which is anytime they are parked.)

+one on tenders.

Are you running heavy weight oil? I ran 20/50 for an oil change and it wouldn't start for shat below 65 degrees. Went back to the reccomended viscocity and no more starting issues.

That's even with the battery tender still connected. I''ll disconnect tender and measure. After the first totally cold start it's usually a start right up. I ask about the battery because it's possible it's the starter. I got it to start after many tries this morning, was on tender all night. Vexxing. Both of my Harleys can sit for a month and fire right up.

Good thought. Am using HD Syn3 oil, which is 20-50. It's due for an oil change. Will get some lighter oil.

Living in Cali, you should be fine with 20W-50 year-round.
I used to switch to 10W-40 for the winter in Colorado but decided to stay on 20/50 a couple of years back.

Definitely get a tender, I'm still on my original battery.

IMO the HD oil (Citgo) is crap. Getting it out of my engine dropped my peak temp 5 degrees. Also it's made by Communists. Live to Ride, Ride to Live!! Haaarleeee!!!

Sorry guys, I had to.
