Very little spark and intermittenly at no. 1
Today with a fully charged battery the ohms reading of the primary post at the coil is 2.7 and the secondary is 10,000. However the voltage reading on number one is 4.86 and 11.82 on number two. I am considering taking all the grounds down and wiping everything clean that reconnecting is this something that I should do. I went through the entire voes system last night and it checked out. really the problems looks like a weak spark at at number one but I can't tell what is causing it. Thanks again for the help, I am about at wits end but can't give up because I want to find what has caused me to loose 4 riding days.

Swap the 2 plug wires. If the problem moves to the back cylinder, you've found the source. If it doesn't, you have something else going on. Could also be a bad coil, shorting at the connection for the first plug wire. And make sure you are using proper plug wires that fit right.

Haven't I isolated the problem to the part of the wiring before the sensor/module con
I will change wiring to plugs but I thought by doing the voltage test at the module side of the sensor/module connector that the problem was isolated to wiring before this connector to the battery?

As I said above in post #4, no you haven't. You stated your problem is that the front cylinder fires intermittently. Is that the problem we are chasing here? If that's the case, then you need to look for that, not other systems like charging. It's like saying: Doc, I can't breath, and the doc then starts examining your toe nails and says, Ahh, you have some dirt here.
If the rear cylinder is firing OK, and only the front cylinder is not working, then we can pretty well assume that the ignition control module is OK. Otherwise, both would fire intermittently or not at all (more likely). You have to look where the 2 spark flows are separate. That would be the thing on the end of the cam shaft that the pickup senses, the coil, the plug wires or the plugs, if it is a spark issue. If it's not a spark issue, then intake manifold gasket, lifters, valves.

swapped plug wires same result. High resistence at
I found high resistance at the ground for the ignition module which is attached to the 30 amp circuit breaker. I removed the lead which travels up the backbone to the voltage regulator and found high resistance in this circuit.
The manual says there should be little or none in this test. I however accidently blew the breaker because I thought the negative battery cable was disconnected. When I attempted to remove the breaker it sparked and I am on the way to get a new one. I will report back when I find out if it is the regulator or the breaker. They are interconnected with the first cylinder?

If you have a problem I would suggest you listen to what he says.

Put the meter down and walk away. If switching the plug wires made no difference, you need to perform a compression test.

Its simply fuel? spark? Comp? swap plug wires(and plugs if it was me)
and it still not running rite on front cyl Its mechanical Nothing to do with wiring. Sounds like intake manifold leak or? But mechanical.The book wont help you with this one....common sense is your only friend.
