coils question

[alehman]

Hi all,

I'm getting some weak spark and my coils are testing as 3.8-4.0 ohms across the inputs. I believe the specs for DOHC were about 3 ohms. In your opinions is this the culprit?

Also, I should mention that the plugs are new, the leads are new, the ignition coils tested within specs, but the spark units may also be to blame. Just wanted your thoughts on how I should handle the coils.

is the bike miss firing?..cuz that 250 i just got running looked like it had a weak spark..but then i realized if if i held down the starter button for a lil bit longer,the spark started getting stronger..

nah, it's not really catching at all. It's all right though, I think I have resolved my issue... just found a complete '79k with only 9000 miles on it and runs mint. For 400 bucks, I snatched it right up... haha

Are they stock coils?
Different brands and types of coils
have different amounts of resistance built into the design.
