Thanks for the response. Yeah, I figured it was the regulator. And yes, my battery is fried...confirmed that when I put it on the charger. Good sources on a regulator? eBay?
I'll pick up a new battery and regulator and I should be good to go.
Also, this happened to me on a few mornings: started up just fine, let it idle 3-4 minutes while I got my gear on, drove out of the garage no problem, but when I went to give it a little more throttle to pull out on the road, I lost power/it stalled for 3-4 seconds. Then it recovered from the stall and took off just fine. Happened about 3 mornings about a week ago and that was it. The way it stalled seemed like the ignition cutting out, rather than fuel. Wondering if an electrical issue like I am having could screw up the ignition like that...weird though because it wouldn't happen throughout a ride. The mornings were warm, too...55F.
