Depending how old the motor is a higher viscosity oil might help |

taken from a different suzuki forum but regarding a 1.3 blowing white-light grey smoke... Quote: While "white" smoke does usually indicate water geting into the Combustion-chamber, if it's actually more like light grey, it "might" mean that you're fuel-mixture is just a little rich at start-up which is fairly common ...you might want to pull your plugs and have a look at color of deposits and whether they are heavier in one cylinder.
IMO id be checking plugs, doing a compression test and going from there. my original motor started with light grey smoke.. soon turned into a Cheech and Chong reunion.. (macca's drive thru wouldnt let me 'drive thru'.)
Let us know the outcome mike! |

the plugs were black so i replaced them the smoke has a weird smell to it it doesn't smell like oil burning or anything like that but it does burn your nose if you stand around in it |

You don't need to stick your nose that close to the exhaust pipe

i did a bit of research and i read that smoke like that can be caused by a blocked or malfunctioning PCV valve. Is the PCV valve the nipple looking thing that screws into the manifold near the carby and has the breather hope connected to it? |

if you go to a good workshop that can do a sniff test ( with a machine) it may be worthwhile as this will give you some indication of what it may be. webbers are renowned for being tempramental. |

PCV valve is the plastic thingy that plugs into the top of the rocker cover, it has a hose off it that runs back into the airbox. If you squirt heaps of brake clean or something similar into it then blow it out with compressed air it should come right. You should be able to blow air through it with your mouth one way but not the other. |
