Yamaha 175 CT2 Ocassionally Just Dies

I have a Yamaha CT2 that I'm restoring. It now starts on the second or third kick, and runs well. I put street tires on it and only ride on the street. I've taken it on rides up to 20 miles long. It shifts and revs to the limit just fine, but occasionally it will just die when I come to a stop sign, but not all the time, just once in a while. At first I thought it was just because it wasn't warm yet, but on my longest ride, it only happened after about 15 miles, so it was plenty warm by then. After it dies, after several kicks, it starts back up, and I can ride it again until it again chooses to die.

I've cleaned the carb and all the jets, but not rebuilt it. I've tried both the stock pipe and an expansion chamber (still dies using either) so I don't think it's clogged with carbon. I've replace the points and plug, but not the condenser. The timing has been set with a dial gauge. Spark seems a bit weak in my experience, but it will always start. Can magnetos die?

So what should I try next? I'd appreciate a reply to my email address [email protected] as I don't know how often I can check back with the forum. Bike is great fun, but frustrating waiting for it to die at every stop.
