Fellow in UK picked up '09 from dealer after service.

"Suddenly there was a hammering sound from the engine, as if a midget was forging a sword, and the engine started moving very violently from left to right as if the cylinders went into overdrive. The RPM's went up and down at random a couple of times, and shifting didn't really have an effect on my RPM's or speed.

After getting off from the bike I noticed the exhaust was smoking like crazy, with thick white smoke. I made a short video on my phone, but it doesn't show well on it. The smoke was about 3 times as impressive as it looks like on the video:

The exhaust kept smoking for a good 7-10 minutes, with a very strong smell of chemicals or burning plastic."

Yeah, it sounds exactly like the broken boot problem... Spark is arcing to the valve cover.

New set of NGK boots will have it right as rain.
