Heard some good reviews of the Champion CJ7Y low profile spark plug. Thinking of getting a Champion EZ Start Spark Plug replacement. Should I be worried that some of these brand name plugs maybe too hot for a 2 stroke ??
That's the only type of plug boot I use and the one I'm constantly recommending here. If you really want to be anal about "securing everything" do what I do and solder the plug wire's conductor to the metal connector. You'll have a electrical connection that you'll never have to worry about again. Too bad the other end at the CDI doesn't lend itself to soldering too.
As for Champion plugs, I've used, and had good luck with a Champion 811 or L82C plug. I couldn't tell any difference between it and the more commonly favored NGK.
As for a 'Low Profile' or a 'shorty' plug I've used an Autolite 2976 where frame clearance was a problem. It too performed well.
