        Not an ass, Mike, just a complete moron.

        Okay, I didn't know what it meant either.

            Dunno about that, but I've heard of coils that would test out fine cold, but start to behave erratically and fail as they heat up.

                That's what I meant.

                  Yes. A faulty coil will do this when it heats up. When the coil heats and expands, the windings separate, which weakens the boost. Could even kill it altogether...

                    My comment doesn't play into which one is better than the other. If they are both new, probably very minor difference if at all.

BTDT. Not sure how to check wires to see if they have gone bad. But wires are cheap and never a bad idea to replace when old. Also the wires and connections feeding the coils are often suspect. Especially the ground.
                      Once again Hoomgar comes through with the answer to my question. I want to replace my plug wires before there is a problem, who knows how old the wires on the bike are and I was curious about the glued on wires, I've never seen that before. Anything I should know before I start screwing with it?

                        Yeah. Don't. If it's working, leave it alone. If performance starts to suffer, and you can trace the problem to the wires, replace them at that time. This fix-it-if-it-breaks policy will save you money and grief.

                          Here's a quote from Motor Cyclist Magazine, December, 1984 regarding a restoration of a 79 GS1000:

                          "...If you own a stock GS1000, you own a set of weak ignition coils. Like most other OEM motorcycle coils, Suzuki ignition coils are poor performers. Low spark energy is partially to blame for slow warm-up and overly sensitive carburetor tuning. An engine does not have to miss, backfire or burn holes in pistons to have ignition problems.
                          Since we chose Dyna for our ignition, it only made sense to use a set of its coils and wires, too. They are easy to install, more than double the energy output from stock and are more reliable. You should also change the plug wires which are molded into the stock coils.
                          ..... if you have to choose between an electronic ignition and a set of coils, leave the points on and take the coils. ....."

                              Well I just put on Accel coils on my GS850l and they work great ,I had to bump up the pilot jet but that was easy.Oh yeah make sure you get coils that are made for your bike ignition ,ether induction or CDI .

                                Stock coils OK

                                I was just wondering if there was a good way to get new wires on the stock coils without introducing unwanted resistance on the wires. I think that they are not meant to be removed from the coils. I would like replace the spark plug wires however, because the bike has 30,000 miles on it.
