I recently purchased an 81 Suzuki GS450L, my very first bike. I'm not getting a spark. When it dies, it does so silently. No backfire, sputtering, etc.
My first thought was that it had aftermarket handle bars and it might have an issue in the emergency cutoff, but that should result in no power being sent to spark plug. That isn't what is happening.
My testing so far has consisted of the following.
- I took a spare spark plug and grounded it to the engine block.
- I'm getting no visible spark.
- I used a non contact voltage detector and connected it to the spark plug wire.
- It shows a series of evenly spaced pulses as I try to turn the engine over, as would be expected.
When I have time later tonight I'm going to use my multimeter to determine exactly what kind of voltage / amperage I'm getting at the plug.. What else should I be looking at / considering?
