Motorcycle Repair: gt750 oil from exaust, running on only 2 cyl/w spark, water buffalo, exaust

Question
I have a '76 gt750 water buffalo, it is only running on 2 cylinders, has spark on the 3rd, good compression. Has oil coming from the exaust on the cylinder that is not running, and the plug is not fowled, any idea???

Answer
Hi Shawn,
  First thing I need to know is .....Have you done a compression test with a gauge and what numbers have you gotten?

  Afew things you can try (if you havent allready)switch plugs from a good cylinder to the bad one and see what happens...does the skip follow the plug or does it stay on the suspect cylinder....

   Put just a little premix down the plug hole on the bad cylinder, then start the bike, will it run on the bad cylinder now?

Let me know
