Pretty new battery (not a cheap one either), and bike is barely cranking and not starting. I put the new battery in about 3 months ago, but lately it was slow to crank and start. Did not fire up this AM, so I put it on a battery tender. Says it's a full charge now, but still very slow crank and no start.

Thoughts?

Anyone have experience with aftermarket starters? OEM is $350; Aftermarket ~ $100. A bit concerned about price of OEM and quality of aftermarket.

I'd wager that the starter is not the issue. They rarely ever go out or have problems on an 1100.

Have you had the battery load tested?

What is your battery voltage when cranking?

Have you tested the reg/rec?

Have you cleaned the frame ground where the negative cable attaches to it?

Those 4 tests should always be done before spending money on something.

On any electrical component..always go EOM. You get what you pay for.

Mick, thanks. Cleaned frame ground, no change. Will put volt meter on battery. Unless it got cooked by bad voltage regulator, I'd be surprised as battery is new but will check. I replaced the rectifier 6 years and 35,000 miles ago. Maybe its gone bad (again). Re: OEM, yeah that was my thought, too. Amazon/Ebay ones just look cheap, and you can't find any reviews on them at all.

Mick, you're a genius! Couldn't find the voltmeter, but I did have my old battery that I had put on the charger just for grins. I had swapped it back in January as I was having trouble with cold starts (< 30 deg. F). Swapped the battery and it started right up. Now I need to understand why my YUASA battery sh!t the bed.

redcat:

For a bike that -cranks- but doesn't fire... when in doubt, test/swap the battery first thing. I deal with dozens of 'won't start for some reason' bikes each month... I get great deals buying 'non-starting' bikes, knowing that 90% of the time the answer is "bad battery"... I play those odds with my own precious money, and I win frequently. Hell, I had to learn to NOT slap the jump-pack on the bike and start it right up in front of the seller... 'cuz then the price firms up. I just play the odds, and trust that 90% of the time... it's the battery.

So I don't care how reputable is the battery manufacturer, I don't care how new the battery is, I don't care how "advanced" battery tech has become. I've seen newer batteries from reputable companies fail far too often. 90% of the time, it's the damned battery...

Mind you, the other 10% of the time it's not the battery. And that can be hell on wheels to diagnose and fix.

My 2nd rule of thumb, BTW: If it's not the battery... 9% of that remaining 10% is "it's the carbs."

For a bike that doesn't crank. God help you. That's a swamp full of alligators for sure. Anything from a bad clutch-pull-switch to "the bike is toast"...

Lesson learned for certain!
