Well this week was the first time I had trouble with the bike as it lost power on the freeway. Towed it back to my garage. battery was incredibly weak so I suspect the stator. Joined gz250bike to looks for suggestions if my best efforts fail me. Been commuting for a couple years, and I'm a big fan of Aerostich, as my suit came in handy when I hit a deer last year. Both the deer and my headlight were injured, I was fine. Thanks for what looks like a wonderful and supportive community of riders. Looking forward to learning more.

Welcome to the forum. Hope you get it figured out on the power loss. As you already know, ATGATT.

I'd give the battery a good charge overnight with an auxiliary charger, then make the following simple test.

At least three hours after I had fully charged the battery, and removed the auxiliary charger, I'd hook up a voltmeter to the battery + and - terminals, and take the following readings.

- The voltage just sitting, with nothing turned on, will show me the state of charge and/or condition of the battery.
- The voltage when I switch on the ignition and headlight comes on, is also of interest.
- While holding the start button in to crank the engine, voltage will drop to some lower value.
- Finally, after starting, and running fast (~2000 rpm) with the choke on, the voltage should rise to its highest value.

From these numbers, we can tell a lot about the battery, and the charging system.

I have a voltmeter but have not tested the battery with it yet. The bike is on a charger and has been since Monday. It turns over but there seems to be no "ignition" sounds. And it seems to lose charge VERY quickly. As soon as it lost power on Monday I pulled over to the side of the road as AS SOON as I pulled the clutch in it INSTANTLY died. No juice to even try to restart it. So I kind of think it has something to do with electrical, but even at a "full charge" it does not start. Anxious to try a new spark plug tomorrow, though, and continue on my journey of learning.
