Speed Triple Smoking...

Hi guys ,This is my first post.I have owned a Street Triple since new in 2009 and also had an Aprilia Tuono,which was stolen last year.Well,I recently bought a 2006 Speed Triple in burnt yellow with all the Triumph extras and only 8000 miles on the clock.I already put 2000 miles on it and loved every minute.Anyway ,I was riding through town yesterday and had stopped at traffic lights.The engine was getting hot and the temperature indicator was 3 bars above normal running.There was a slight following wind ,and I suddenly smelled exhaust smoke and a second later saw smoke blowing past me.Looking down to my right I was horrified to see a fair amount of smoke from the Arrow 3 into 1.I rode on about a mile and the temperature was back to normal so I stopped to check for smoke but it had stopped.When I got home I checked the oil level which was OK.But surely a bike with relatively low mileage should not smoke like that?I am a bit worried now.The smoke was grey/white.I recently changed the coolant and according to the Haynes manual it takes 2.8 litres.But the owners handbook states 2 litres,which is all I could get in it.

 

Merseyside...and it was a cool day.I been out today on it and no sign of any smoke....but I didn't get stuck in any traffic so no overheating.

 

It was definitely exhaust smoke.The bike has not smoked like that before or since.Anyway,I have a theory.Just prior to the smoking I had overtaken a car by cracking open the throttle in 3rd gear ,revving the engine to about 8000rpm then slamming the throttle shut on a downhill section and bringing it to a stop by engine braking in 2nd gear.(Not how I normally ride ..I was carried away by the jet engine like howl from the exhaust.)I think It may have sucked a little oil past the rings into the combustion chamber.I rode it yesterday and no sign of any smoke.Since I changed the coolant I did a 220 mile run with no problems .I was worried about only getting 2litres of coolant in,but apparently that is normal.
