ECU, Coils, or ???? -- Legend TT
What are the symptoms of a failing ECU? Failing coils? Bad switch (clutch)?
I have a 2000 Legend TT, bought new in early '01, with about 14k on it (I have 2 other motorcycles and I also ride bicycles a lot, so the Legend doesn't get a lot of mileage). About 1 month ago, I was riding home in heavy, heavy rain. While stopped in the left turn lane, waiting for traffic to clear, nearly drowning (did I mention it was raining?), the Legend just quit. All three cylinders at once. No hiccups, no misses, just stopped, like I flipped the kill switch to off (I didn't). It wouldn't start -- almost like the battery was dead. The motor would just turn over very slowly, never quite catching. I pushed it in the heavy traffic (did I mention it was raining -- and I was in 5 pm rush hour traffic) about 400 yards until I could pull into a driveway and let the rain fall, and the traffic clear. After about an hour, the rain had quit, rush hour traffic had died down, and the bike started right up, like nothing had happened. I rode it on home, wondering what the heck, and pulled into the garage. I put the charger on the batteryand brought the battery (a gel cell less than 1 year old) back up to full charge, just in case.
I've ridden it several more times since then -- no apparent problems until today.
Today (clear & cool, no rain), I took the Legend out for a short ride. I had to stop for a l-o-n-g traffic light, and the bike stopped again. No hiccups, no misses, just quit. This time it started right back up w/o problems. I rode it on to my destination, about a mile further, pulled into the parking spot, and it died again. Since I was at my destination, I parked, ran my errand, came back out, and the bike started right up, but died when I pulled up to a stop sign leaving the parking lot. Again, it started right back up, and it didn't quit again on this short ride, but I didn't have to stop again on the return trip back home.
Bike had a full tune up @ 12K, per the guidelines in the shop manual. It did sit for 9 weeks last summer (June-July), after the tune-up, while my broken pelvis was healing, but started up immediately when I was released to ride again.
What should I check? I'm stumped!! I want to have the confidence in my Legend again.
