I'll be replacing mine shortly not that there's anything wrong with it just don't want to leave it to chance , I'll be putting a gel filled marine battery in like o did with my last bike .
I just chucked a new battery in my 2 weeks ago. The old one was bit slow starting on one of the cooler mornings so I had it in the charger overnight but it was still a bit lazy. Like you @Wrecka I don't like leaving it to chance so I got a new one (didn't cost much more than a tow I suppose) and I keep the old one on the tender 24/7 as a stand-by or if anyone needs one in a pinch.
btw I got the Deka gel, made in USA (owned by H-D now I believe) and it seems to be a pretty solid unit. I am sure there are Marine equivalents out there as long as it has the CCA's and isn't made in china.
Maybe the reason it felt like the brakes were coming on was because when the main fuse went out and he lost ignition and he basically had engine braking.
Spoke to the service manager today
Apparently the rear brake locked up on them during a test ride.
They went through the brakes and he said the only thing they found was the rear brake lever was adjusted to low
They raised it up and have been unable to get it to lock up since.
