    Spark plug boot question

    So I have been tearing apart my gs650g, and was wondering something. One of the boots (Coil>Spark plug boot) were missing and replaced with some copper wire poked through the coil's wire and connected to the plug. So I assume the previous owner just lost it or something to that nature and didn't want to spend anything (still gets spark though). I was wondering if all I'd have to do is buy a new boot and connect it.

    Sorry, I haven't had time to get to my bike the past week to get a picture or even work on it so you're just going to have to use your imagination

    you are correct, just snip about 5mm off the end of the lead to get a nice clean end and screw a new plug cap on. may be worth replacing all 4 while you are at it
    1978 GS1085.

    Just remember, an opinion without 3.14 is just an onion!

      Yes, the dealer should stock that boot. Most any bike shop, actually.

        That's exactly what I was thinking. I'll probably snip the recommended 5mm on all and replaced the boots

          Here you go, you can't be the price!
          Otherwise about $15 apiece.

              Most GS bikes use two long caps and two short. Best to make sure to get the proper size. http://www.z1enterprises.com/ListIte...x?keywords=ngk
