    This worked for me. Had a hard starting issue for years. Replaced coils, plug wires, plugs, signal generator, and alternator. Rebuilt carbs....the Whole Nine Yards.🙄🙄Once I did THIS, the issue completely disappeared! Starts right up, cold or hot. Great upload.👍👍👍

    You should connect the ground to the negative terminal on the battery. Grounds should be at the first point available and you've doubled the length of your ground lead to ground somewhere else. Plus, there's no better ground than the neg terminal, especially if it's very close.
    Also, and only because you said to place the fuse "in the middle", I wanted to point out to others that you don't really want the fuse in the middle of the wire. The closer the fuse is to the battery, the more likely it is for the fuse to do it's job if there's a short, as it lessens the amount of wire before the fuse which can short without the safety of a fuse.
    Not trying to be "that guy", just thought I'd share some tips. Thanks for the video!

    Hey Kat Mech,
    I am again in need of your great wisdom. 1990 Kat 600, Vance and Hines 4to1. Just ultrasonic cleaned and rebuilt the carbs, but I still have a weird mid-range misfire... Measured the header temps with an IR thermometer (at idle) and found that header #2 is only getting to 195*F while the other pipes are getting to 500*F. Did a compression test and all 4 cylinders were making relatively similar compression. Tested the wire/plug and was getting a baby little spark out of #2. Took a look inside the #2 plug boot and the contact that grips the spark plug looked brand new. The other 3 plug boot contacts look grayed. Voltage to coils is sitting just over 11V.
    Coil relay mod? New coils? I'm at a loss.
    Always appreciate your wisdom. Thank you.

      Theirs a few things I’d check. Make sure the holes that allow excess water to leave the spark plug area are clean (check my spark plug video). Then I’d swap everything between the spark plugs and the coils and making sure the spark plug is contacting clean metal. After that I’d throw in the coil relay mod to increase the voltage a little.

      I can’t remember for sure. The original harness uses quite thin wires. I believe they might have been 12 or 14. That being said I always used a slightly thicker gauge everywhere I had to rewire which was most of the harness because of rodent damage. I believe I was using mostly 8 and or 10 for everything I redid. The main thing when choosing wire sizes for this is to not go thinner. I like to go 1-2 sizes thicker at most if I think the wires are too thin for long term durability.

      @@damyonchrysler7818 this could be any number of problems. First check if the battery is able to hold enough charge to do anything. Then I would check fuses to see if any have issues. After that I would look at a wiring diagram to make sure you connected the ignition wires correctly. Then I would start by checking the volts going through different parts of the harness to see where the issue is. Old katanas frequently have issues at the switches themselves so I’d test to see if the starter button is actually able to complete a circuit along with the kill switch. Then check if the starter is able to turn over by connecting the battery directly to the starter. Could always be a starter relay problem too. Considering the ignition wires were cut I’d say the most likely problem is you didn’t connect them together properly.

      I have not heard of that before. However, you can only get so much power out of a Suzuki Katana engine and having a different CDI setup will only help a little bit. If your looking for more power but want to keep the same bike, I recommend you put a bandit 1200 engine in. Most modifications increase power slightly but the difference is often negligible. Otherwise, if you want more power I recommend a different bike.

    Sorry to burst your bubble Buuuuuuut relays only act as a switch they don't increase voltage, only transformers do that either step up the voltage or step it down.

      They don't increase which is correct, but in old bikes such as mine, the wires don't carry the same voltage anymore. This relay installs new wires that bring it back to original spec.
