Fat Blue Spark

[mike10]

I just did the coil Mod. on my 1980 GS1000. No points ignition. I hear Guys talk about a thick blue spark at the spark plugs. I have never had that. My spark is kind a thin and orange, a lot of sparks, just not thick or blue. After the modification they look the same as before.

No worry Mike. How does the bike run?

I have not started it yet I don't have the valve cover and tank on it. Waiting for valve cover gasket. After the Coil Mod. I just stuck a plug in the lead grounded it on the head and cranked it over to make sure it had spark. I guess I expected Lighting! It ran fine before I took it apart.

Have you replaced the plug Caps?

Your spark should be blue/white (best seen in the dark)

No, I should get new leads but it looks like a pain in the butt to replace them. I took the caps off trimmed the lead and screwed them back on also wrapped them with electrical tape. I would like new coils and leads but they cost too much.
