    Re: Spark plug wire and boot.

    any hypo shop that has bulk wire since you only need a foot and will need to cut that. 7mm good core and good silicone boot will make all the difference in the world. i got mine from napa and also a race car place that i cannot remember the name of for the life of me.

    One of the weak links on these bicycle motor kits is the plug/wire/cap.

    Do it now.

    Re: Spark plug wire and boot.

    I've been looking at MSD and Dyna. MSD is what we use on our race car's and they have many upgrades for small engine and motorcycles. Dyna is mostly for motorcycles. But I have not found anything that would seem to work. Maybe somebody with more knowledge will have better luck then me.
    Do any of you guy's remember the Answer Roost Boost? It's basically a amp for your ignition. I'm sure I could get one to work but they stopped making them 10 years ago. I've looked for one like crazy but have not found one.
    Dyna has one, but it is for 4cyclinder motorcycle.

    Re: Spark plug wire and boot.

    How do you guys attach the new spark plug wire to the CDI?
    And is there a part number for a better spark plug?

    The plug wire just screws out and the new one screws in. There's a little threaded peice in the cdi....................

    Re: Spark plug wire and boot.

    As Ilikea says, there is a screw (sheet metal threads) inside the CDI plug wire hole...just unscrew the old one, screw the new one in. You may need to make a starter hole in the new wire center conductor with a tiny screw or awl or something. Also use some silicone grease or lube on the OD of the new wire. This will help it go in and seal it. (don't use any regular petroleum grease)

    Re: Spark plug wire and boot.

    Cool, what about the spark plug? Should I get a new one, if so what kind of plug. Or is the stock plug good enough?

    I'm still running the stock plug in both of my bikes. But I'll probably change them out this summer. I figure if it aint broke don't fix it................

    I like the NGK B5HS, but they can be a bit tough to find locally. I ordered from the web.....eBay! But also try a motorcyle shop.....in Seattle a bit rare, but if you make it up Aurora/99, Lynnwood area, lots of MC shops up there. Call 'em - let me know, too!:D

    Spark plug wire question

    I went out and bought a NGK B6HS plug with no problem. But i still need a 7mm wire. I have seen other spark plug wires but they were so long and look nothing like the inside of the stock one. What should i look for when i look at the wires, and if i bought one would i be able to screw the new one back on the cdi?

    Re: Spark plug wire question

    They usually sell wire by the foot...cut it too fit your needs. If you have trouble finding the 7mm wire you could go with the 8mm. You will just need to trim a little off the insulator off to get it to fit inside the CDI.

    And yes you just twist the wire on to the CDI

    Copper or wire core if you can find it. Worth every penny.

    Resistive type spark plug cable

    I was just wondering if performance would suffer if a carbon type spark wire is used? It adds some resistance and I was wondering if spark is affected.
    Thanks.

    Re: Resistive type spark plug cable

    We have found no performance difference between a copper core and carbon type resistor wire. The major advantage of the resistor wire is that if you use an electronic speedo it won't reset itself all the time.
