    Points spark, not plugs 1978 GS1000

    Misses over 4000 RPM. Removed points cover, 1-4 points arching like crazy, very weak spark at points. Swapped coil wires from 2/3, coil is ok. Points and condensers have 600 miles. Ideas?

    Points arching is a sign of a bad condenser, try one of your old ones if you still have them

      Just went through this. My condensers were shot. Replace your points and condensers, and you should be good again.

        Even if they have "only" 600 miles on them, try some condensors with ZERO miles on them.

          Some of them last a long time. Some of them don't last at all. Some just don't work right even when new.

            If the points have been arcing for 600 miles, it's apretty safe bet they are toast by now. Most likely from faulty condensers. Points and condensers are not expensive.
            I would replace both. I get them from. http://www.crc2onlinecatalog.com/Index_Main_Frame.htm

              Man that is inexpensive. OEM would be close to a hundred dollars.

                Thanks to all. Switched condensers and is definitely a bad one. Bit the bullet and ordered OEM from the dealer. Cheap aftermarket parts is what caused this problem

                  What did they cost? I bought OEM from bike Bandit for my free 850G, and I'm pretty sure it killed a hundred dollars.

                    With my discount, 2 condensers were $25. The points cleaned up. Runs like a watch.
