I can no longer kill the engine with the choke, guess I will have to hook up the kill switch now!

Cool!!! I thought changing the plug wire would be more complicated...thanks for spelling it out for us.

What wire size did you use?

7mm seems to work best

Hi Cruiser,

I received the plug wire yesterday and it does make a big difference in the overall performance of my bike. My immediate impression was how easily the bike started (temperature in the teens this morning). The engine idles a bit more smoothly also. This is an easy and helpful upgrade!
Thanks so much!
