Weird starting issue
08 Nighster, Power Commander, SE intake, and "Straight Shots" exhaust...
Only 1300 miles, never ridden in bad weather.
Sometimes when I start, it'll start to crank, then just sit there and do nothing for a split-second or 2, and then start right up. It's like the starter motor is stalling (no clicking or anything like a dead battery, just a pause in the starter turning over it sounds like).
Any idea what could cause this? I've never had it not start, but it's a little disconcerting.

Charge the battery and check if that solves it.
I think it's "reaching the end of its usable life"...
(a few years ago, mine did that too. And even though I always connected it to a trickle charger, The problem was only solved when I put in a new battery)

Check the battery cables. Mine does it if the negative is a little loose.

Thanks, battery cables seems like a likely culprit, I was thinking that or relay.
Shouldn't a battery last more like 5 years??

It could be the relays going bad, too. I've heard of people keeping their battery for at least 6 years. It should last at least 4 or 5 as long as you don't repeatedly run it dead I would think.

As mentioned, relays are notorious on these bikes. Check my sig for part numbers.

The water-logged OEM starter/system relay on 2007-2009 Sportsters is a OMRON G8H-UA-007401, but this can be crossed over to some automotive apps: Borg Warner R3154, Gp Sorenson 41-5154, Niehoff RL 35381 are examples. Good luck!

Battery should last a good 3-5 years. It's probably a loose cable. Check both ends of the cables and don't just shake 'em with your hands, get a wrench on 'em. Sporty's are infamous for vibrating battery cables loose. If that's not it, it may be a relay.

My battery was 2years old when it went bad.
The bike had been standing still for over 3months while it was being converted to 1200, and there was no trickle charger attached. I guess that that's what killed it.

Ok, I'll try to get a spare relay (from other threads seems like a good thing to have anyway, though mine doesn't really get wet), and check the battery cables. If that doesn't take care of it, I'll just look for a new battery.
What kind of batteries do folks use?

So typical of the sportster.The starter is trying to overcome the point of most compression.The stock sportster starter motor is a tad too small.
