About three weeks ago, I tried to start my lovely 2003 Bullet ES after sitting for about three weeks (life got busy in a motorcycle-unfriendly manner), and I had a hell of a time getting her to start. At the time, she had a little under a gallon of relatively fresh nonoxygenated premium fuel, the stock Micarb 28mm, a healthy battery, and healthy oil. She took about five to ten minutes of kicking to get her to start, and she had a tendency to die in those first few minutes, so I nursed the throttle while preparing for a ride. She'd run a minute or two, then stall, and I'd try to start her again. She'd run feebly for ten to thirty seconds, and not really respond to the throttle. Eventually, she quit starting.
Fast forward to this weekend. I replaced a fouled plug, installed a Mikuni VM32 that I had been saving for a special occasion, and replaced the existing fuel with a gallon of fresh nonoxygenated premium. I checked that everything operated, and tried to get her to start again to no avail. I began to suspect that spark may be a problem, so I cracked open Google, and broke out my multimeter. I've tested the coil, and it appears to check out based on a number of resources I'd found. The battery is still good, reading about 12.6v. I got behind the battery to check that black wire from the points that likes to come undone. I checked the fuse, and looked for loose or frayed wires. I checked for spark at the plug, and to my surprise, I had none.
With the key on, the ammeter doesn't react when I switch the kill switch to the run position, or try to kick the bike. The electric start never really worked, but it decided to cooperate long enough today to show that it too couldn't get the poor bike to start. The coil tests okay, the battery is still strong, the plug is brand new, the plug wire checked out, the gas is fresh, and the points looked clean. I didn't get a chance to dig behind the nacelle in search of answers tonight, and I'm not sure where to go from here. Most of the searching I've done pointed to either the coil or that black wire behind the battery, but those checked out fine for me.
I digress. I'm interested in hearing any input the lot of you might have. I'm pretty green at motorcycles, honestly, but I'm handy enough with a spanner and almost stupid enough to try anything. Almost.
