I have a 02 F4i and have it stored away for winter. I start it and let it run once a week to make sure everything is good with the bike. Recently I have notice there is really thick white smoke during the first minute or so of it running. After that it is just fine. The oil was changed and I made sure there was a full tank of gas with Stabil in it. Is the Stabil causing this smoke or is it something more serious??Thanks in advance for your input.

 

Possibly some moderate flooding? Is it hard at all to start the bike? I know with some of my older cars after they flooded once they got going, a TON of blueish-whiteish smoke came out of them (enough to completely fill the garage at times)

my guess is it's just burning off some extra gas. Dark smoke is bad, but I think white smoke is ok.

 

dont worry about the white smoke... that's just due to the condensation thats built up inside your pipes. just make sure that it doesn't smell bad, cuz that could be burning oil

 

white oderless smoke is condensation as stated above.

Oil would be blueish white and smell bad.

antifreeze can burn thick white smoke, but it will smell really sweet.

fuel is black smoke, nothing to worry about there.

 

Thanks guys. It was just weird that out of no where it started doing it. I didn't thank it was a huge problem but I wanted to make sure. Thanks for the info

 

i let my bike sit without starting it for nearly 4 months and then started it up to move it into my house. usually letting it sit this long doesn't mean there's a problem but if it does it more often then it could be a sign that the valve guides are starting to get worn (a sign of hard riding). when this happens it allows oil to slowly drip down into the chamber whilethe bikeis not running. This oil then burns off when you first start the bike. it will burn white with a blueish hue and smell like burned oil and fuel.

you'll know it if the bike is burning coolant becasue it will look like this

I just started it today and it didnt happen. so maybe the problem is over.
