Smoking on cold start.

[Phil3]

I am writing to this forum despite having a Tuono, as it is doing something that may occur on Milles as well. I have not gotten much response on the Tuono forum.

When firing up my new 2004 Tuono (796 miles), when stone cold, on full choke, it puts out a puff of whitish smoke. This clears within 1 to 1-1/2 seconds at most. It will do this if it sits for as little as 30 hours. If fired when warm, after 30 minutes, no smoke at all. No smoke if you gun the engine. I first noticed this after the first service at 625 miles. It may or may not have been smoking before the service. The engine runs well, and since the 625 mile service, it looks like no oil has been used. The only thing I have noticed is that the oil level is at least 1/2" or more above the MAX line if the oil is checked within 30 seconds of stopping a hot engine. Fact is, I couldn't really see the top of the oil, coming down only after a few minutes. Is it possible an overfull tank could cause the smoking?

I can't believe smoke on startup is normal in this day and age on a $13k bike!

Thoughts?

It takes a couple of seconds for the sensors to read and the ECU to adjust the mixture. No big deal. The oil will take care of itself.... It will just end up in your airbox if it's overfilled. Wipe it out next time you clean the airfilter and all is well. It's normal for a new owner to be wound a little tight about his big investment but no worrys... The Mille engine is a tried and true beast.

You may just be seeing condensation (white smoke) when starting a cold engine.

A lot of people mistake water vapor for smoke. If it has a plastic smell to it then it could be a coolant leak but I would guess that its just water vapor.

Your oil shouldn't be that full. Drain a little out.
