After my 2004 battery suffered a slow death I decided it was time to invest in a new battery (OEM Honda same specs) which I did last week. After staring for a couple of times and a few hours I noticed the battery got weak, like the old one. Yet after a couple of ours more the bike started to foulter and would only run idle (the red ignition button light started flickering in sync with the RPM). What is happeining to my bike? I put in a fresh battery from a friend of mine which solved the problem, but noticed that when I disconnect the + cable of the battery the bike stops. I do not think the new battery is the problem as I charged it with a battery charger and it loads normally. I also verified any problems (of short circuit). My bike is equipped with a VORTEX ignition but also do not suspect that one since the bike (with loaded battery runs 100%). What is the problem? The voltage regulator ? The stator? How can I test?
