Hi all, I just wanted to drop a quick note to everyone saying thanks for the input. It turns out the problem hasn't completely gone away, so I'll be carving out some time in the next few days to look at it some more. I'm beginning to suspect multiple problems, with one masking the other. I'll be trying out all of your suggestions, to the extent I can with a non-running bike. The old battery was definitely dead. It's now only holding 11.7V when charged off the bike. I bought a new AGM to replace it. Update: I went out for a ride shortly after I sent my first email on this subject. The bike rode fine for 3 miles to a stop. I then started the bike again and rode another couple of miles. Pulling away from a stoplight the bike just died again, with the same symptoms as I originally had - headlight on, engine cranking but not catching. I had to put the bike on a trailer to get it home. The petcock was on. It's beginning to sound like there's *also* a fuel flow problem, so I'm going to play near the petcock to see if suction is opening it properly and to see if any of the vacuum hoses leading to the petcock aren't sealed properly. I may also have toasted the petcock gasket when I took it apart. Just in case it -is- electrical, I'm going to see what the voltage draw is on the battery once I get it running again. I wish I'd thought of that earlier. Thanks again, and I'll report back with further progress. Daniel

Ok, new answer. It was the ignition coil. I finally took it into the shop (Mission Motorcycles in Daly City - Doug the mechanic is a KLR rider too, and I recommend both him and the shop) where I gave the full debrief. Apparently the primary circuit in the coil was working fine, but the secondary was putting out less voltage and had more resistance than it should have. Doug installed a new coil and I'm now up and running. By the way - the old, OEM battery wasn't dead. The Battery Tender Jr. I just bought wasn't working at all. I now have a new Battery Tender Plus and the old battery is holding 12.61V after a couple of hours charging and a day on the shelf. If anyone near San Francisco needs a stock battery, drop me a line and you can have it. Thanks, Daniel

Charlie-- Don't recall that we ever used anything other than vaccum line; ordinarly vinal used for agriculture sprayers would work also. revmaaatin.
