Bought this 2001 Shadow 750 ACE (C3) last summer and rode it without trouble until late Fall. Winterized it (oil change, wash, chain lube, fog cylinders, stabilize fuel, battery on tender, etc) and it started right up this Spring.
Have ridden twice this Spring; 1st time about 55 miles on rural highway, and the 2nd, about 200 miles on rural highways; both times, held speed to 60 mph or lower.
PROBLEM: on both rides, when cruising at about 55 mph, suddenly the engine 'cuts out' for a 1/2 second, then picks up again where it left off. When the power is off, its like someone had turned the ignition off for half a second, then turned it back on again. No sputtering when picks up again just continues on like nothing had happened, but often backfires once when the engine comes back 'on' again. This has happened about a half-dozen times now, and I cannot predict when it will happen.
Another curious thing was that when I pulled over the first time this happened, I could not find neutral - green light would just not light up. When I turned the ignition off and on again, the neutral light was working again, the bike started up as it usually does, and I was on my way again.
This is concerning when it happens when I'm cruising, but downright dangerous when I'm trying to accelerate to pass another vehicle!
Any ideas as to what is happening? And how to fix it/prevent it from happening again? I'm NOT a mechanic by any measure....
Thanks for your help.
