This is a strange one, boys. My '06 (carbs) -- relatively fresh at 18,000 miles -- enjoys inexplicably giving up the ghost on me during a ride. Here's the scenario: Putting along (or zooming, it happens at any speed) and the motor will simply stop. No sputtering, wheeze, or cough. Just an instant motor cut-out. No loss of electrics and the backwheel doesn't lock up (although it will if I try an immediate bump-start -- there's no bump starting this bike.) It has nothing to do with the side-stand cut-off switch. I think there is something going on with the ignition. When the bike cuts out the motor will usually fire back up if I wiggle my key. But there's nothing scientific to how I wiggle it -- sometimes it works, sometimes it doesn't (I'd say it works 75% of the time). But I cannot recreate the engine cut-out by wiggling the key, only restart the motor. There is nothing obviously wrong or out-of-place with the ignition barrel -- but as you know it's a pretty neatly packaged little thing and doesn't reveal much about its inner workings. What's strange is that the motor doesn't "fire up" in the conventional way -- instead it instantly resumes its last position in the powerband. It's an extremely uncomfortable and dangerous feeling, rocketing from a coast to 5,000 RPMs, and I'm sure it's hell on the driveline. This bike has been well maintained by professionals. Up to date on all TSBs. I submit myself to the Orange Crush for wisdom and guidance!
