My ignition went wireless

[Dingo]

Yesterday I hooked my battery to a charger, today with topped up battery I was planning on going out for a ride, and had a hard time starting it, once it was running a let it warm up for a while (2-3 minutes) and noticed the the 2 centre exhaust tubes got really hot but outer ones where barely warm.

Well I start checking the usual stuff, gas is fine, spark is fine also, but here's the catch:

With the caps on the plug nothing, but if I unplug them and leave them about half inch from the plug, with the motor on, then they start to fire if they're reconnected they go dead, I'm pretty sure it sounds strange to most, but I'm lost, thing is only the outer 2 cylinders do that if I have the engine running with those 2 unplugged and then place the caps (without touching the plug) the rpm's just start to climb . But once again if I reconnect them they go dead.

I even let it run for about a minute with the air gap and the exhaust has the same temperature in all 4.

What can I do?

Maybe the cap or the cables try switching the plug caps, and check the cable for continuity

I'm not sure but if the wires or more likely the caps are cracked then the electricity might ground from the crack to the cylinder head, bypassing the plug. Get new wires and plugs.

Pull each of the plugs on the outer cylinders one at a time and run it with them grounded to the case (and wear heavy gloves, and hold 'em by the wires!) and see if you're getting spark. May just be time to balance your carbs.

The carbs have been recently cleaned, synced and balanced, I get a spark from all 4, but not while the 2 outer ones are connected, as someone said earlier probably the caps are so cracked that they bypass the plugs actually this is one of my caps:

Anyway on the sohc4 forum they've told me that I'm not running the correct plugs for my bike, and that there's this phenomenon where the spark gets stronger if you unplug the lead and leave an air gap between the plug (useful with flooded engines) and that's all 4 only work when 2 are unplugged.

My 350f was doing the exact same thing after I first bought it.. One of the coils was bad. Bought some dyna coils, new plugs and wires and never had a problem since. I would have just gone with the wires but you can't really change the wires on the stock coils so I just sucked it up and got coils too.

Holy frijoles. Yeah, I take back what I said. To the wire store with ye.

turns out, i'll be in the states next week.

Can I get the caps at any NAPA, Pepboys, autozone type of joint?

Yea, you can get a plug wire kit at those places, I use Advance Auto Parts to buy stuff. Closer to my house. Try to get graphite core wires, they carry better spark to plugs. New boots and your good to go!

I have a set of copper core wires, but i'll see what I can find, I'm currently in Century City CA, so I have no idea what's around here.
