    81 GS650L Not Running Right

    I just purchased a new bike project that has me puzzled. I tried searching the forums with no luck on my specific problem. I tried to start the bike today and could not get all four cylinders to fire. I pulled out each spark plug and tested for compression which checked out a-ok. Checked for spark and all plugs were firing. The two cylinders spark plugs on my left when sitting on the bike are charred back but dry and the two spark plugs on the right side of the engine were black but wet and smelled like gas. I was able to get the bike to idle and after carefully checking the exhaust pipes to see if they were warm the two cylinders on my left were hot and the two cylinders on my right were ice cold. Can anyone point me in the right direction on where to go from here. I have spark and compression on all four cylinders and the two cylinders that were hot are obviously getting gas, and the other two are wet which im assuming that they are also getting gas, but not enough to let her run like she should. I also tried spraying ether into the two cold cylinders with no luck on getting those plugs to fire. Maybe an electrical problem? Thank you in advance for all of you that put forth your two sense.

    Rebuild the carbs and go from there. No short cuts allowed.

      Since the two non-firing cylinders are on different coils I agree with Ed.

        First of all,

        Next, THROW THE ETHER AWAY.

        Third, clean the carbs, as suggested.

        Fourth, while you are waiting for your carbs to soak in the "dip", adjust your valves.

        Fifth, put some new plugs in there, then sync your carbs and RIDE.
