Smoking at start-up...

3 posts in this topic

Guys,

I am getting some white smoke when I start the engine and durning warm-up. Anyone else experiencing this? What could be my issue? Rings? Valve guide seals?

Thanks In Advance!

Dave

White smoke on startup is usually from water condensation inside and usually nothing to worry about. Blue smoke is from oil burning and black smoke is from too rich of air/fuel mixture. If your oil looks like like a milkshake or your coolant level keeps dropping, then you may have something to worry about, but its likely nothing to worry about :)

my "L" does this at startup, particularly if I blip the throttle before it's warmed up. It's sort of hard to tell what color the smoke is, I don't think it's oil smoke (doesn't smell like it). Sometimes it takes some significant cranking to get it started if the bike has been sitting for awhile (especially when it's cold out), and I wonder if this may be the unburnt fuel vaporizing and blowing out the exhaust. Makes me wonder what it would be like to have to kick? Maybe "R" models just start easier?
