Spark cycles

[dna9656]

I bought a tankful of water at ARCO today, got 1/4 the way to work and it crapped out. I got about 1/4 the way home and it crapped out again. I guess some fuel was still in a place where it could get burned.

I got some 1 gallon jugs, my HF siphon squeezer, and got back to the bike on the freeway during rush hour of course. Got the water/gas out and some good gas in but the battery was too far gone. Plenty of biker guys pulled over and offered to help..thanks to all! I got it on the trailer, and got it home with a new tank of gas and got her started. I was cheching to see if I had spark on all cylinders when I found (via timing light) that the left front cylinder is firing at about twice the rate as the others are.

What's up with that? I also learned that I have plenty of signal to the TCI vacuum sensor.

The front left is #2 cylinder...same ignition coil the tach reads.....so unless your tach is reading waaaay high, its probably right. Any chance the other 3 have different plug wires, making it harder to read with inductive clamp?

All plug wirers the same Beldon's metallic core 7mm. available at NAPA in bulk.

Yes, #2 cylinder gives timing pulses to the tach!
