    Oil on sparkplugs

    I have a '79 GS1000e; two of the spark plugs are getting coated with oil, they last about three days before I have to torch the carbon off of the electrode. I'm in the process of taking apart the engine and replacing all the seals which will hopefully fix this issue. This will by my first time working on this type of engine, if I work on it only weekends how long can I expect this to take and have the motor reinstalled on my frame?

    Better do rings as well. My bet is the oil rings are heading soiuth real quick!! Valve stem seals will make it smoke primarily at start up and the smoke disipates rather fast. Oily plugs are more the tip that the oil, rings are allowing bypass at an alarming rate.

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

      If you have all the parts and all the right tools and everything goes as planned then a weekend should be enough time to get the job done. But that's just theory.

      In real life you'll spend the week days sourcing the bits you didn't think you'd need.

      A question for those more familiar with the 1000 motor: Is it necessary to remove the engine from the frame to do the job on the head and barrels?

          Yes the top end can be done in the frame. I took mine apart one evening then took the cylinders to a local guy to hone. I had a spare head that I rebuilt with new seals and valve grind sitting on the shelf waiting so reassembling everything the next weekend went pretty quick. New rings, new valve seals, some gaskets, a few heat cycles for retorquing and it was good to go.
