    Stinky Exhaust

    Hi folks,

    I have a 1980 GS1000 ET and it's running great but after a ride my clothes are pretty smelly of exhaust. I'm not sure if this is normal or not for an older bike. I bought it last year and got the carbs re-done and a few other things taken care of. Someone said it might be a mixture scew or something like that but I'm not very mechanically minded so I'm new to this.

    I've read a few posts on the site and to answer some questions that might come up... there is no smoke coming from the exhaust, dark or any colour, fom start-up or when riding. I have a single exhaust. I changed the oil recently but the smell is the same. When the carbs were done the mechanic did the jets as well. He had a Clymer manual to make sure he did it correctly. RPM idles at around 1.2 and is consistant. The spark plugs have a dark soot on them but are not wet with oil. Normal?

    I don't want to bring this in, mainly for the time it takes so I'd like to try fixing on my own. Unless everything I've mentioned is normal. If so then I'm a happy camper.

    Any input would be appreciated.

      Dark soot means rich mixture. When the mechanic did the jets did he change jets, or just clean things up.

          Humour me, a bit...
          Do you warm the bike up in a garage, or out in the street?

                  In the winter, I make sure it's gonna start before I pull it out of the garage. (steep driveway) I'm usually smelling pretty funky before I can get it outside.

                      After I revived my old GS1100 from a case of "old gas", the exhaust smelled like old gas for about two months afterward. I cleaned everything from the gas tank to the intake and it still smelled bad. It did eventually go away.

                          I've had a case of "old gas" before and it really does linger!:-D

                              My 850 had a windshield on it when I bought it, first one I've had. I liked the windshield but I noticed mild exhaust fumes when riding (stock exhaust, etc.). I know it circulated the air funny, because air would try to get under my shirt in the front. I don't have the w/s any more, and no more fumes either.

                                  I don't have a garage so that's not an option for my clothes. I'm not that dumb!

                                  So the rich mixture is due to the jets? How hard of a fix is that?
