hmmm thought that was blue, so would Mystery Oil or something like that help?

if there is some water in the exaust sometimes it will smoke white

**jmsmilin** · 10-31-2006, 11:11 PM

hopefully its just water, I did just pressure wash it at the car wash...

mine does it, only started doing it now that the outside temp is about plus 3 to 4 degress Cel...does it every year...

Forgot to say, i'm going with the water in the exhaust thing here, hot engine when it's shut off, the cooling down effect causes condensation (again being the time of year), then the next time the engine starts, it heats up the water. make perfect sense to me. mine will start doing this about 2 to 3 minutes after started. And it doesn't smell like burning oil or anything engine wise to me.

I have a 1985 1/2 225 DRS Tri Moto. Lat year mine started to do the same smoke signals. It had great compression. So I know rings and piston were ok. I checked the valve and clearence those to were fine. I took everything apart to inspect the valve guides and seals. To my surprize they were trashed ! After a complete valve job my baby runs like a champ again !!
Not sure if that is what you have or not but this helped me out ?? I am a 2 stroke man myself. But love my Tri Motos !!

Hope this helped some what ??

as it turns out it looks like its just running too rich, as I made adjustments to the carb the smoke and smell went away, plus it runs soo good it cant be rings. Also, the air/mixture screw was all the way in...

not true , i've seen lots of engines smoke like crazy and run and drive great from worn rings . if its running rich it'll have a grayish or black tint to it. unless its just dumping a crazy amount of fuel in then it'll be white but the gas smell would be horrible in that case.
