I'm trying to get my brothers '94 EX ready before we head down to VIR on Saturday. The bike is running kind of rough and someone mentioned that it might be caused by a weak ignition. The bike starts up on one cylinder and then after it idles for a bit it will run on both cylinders.
We put fresh fuel in but it did not seem to help. The igniton coil ignitor is making a buzzing sound so I think it may be caused by that. The manual says you need a special tool to test the IC igniter.
I pulled the plugs and they were black and covered in carbon and smelled strongly of gasoline.
I have two manuals but neither of them say how to test the coils. They just say 2.3-3.5 ohms on the primary and 12-18 ohms on the secondary. What does it mean by primary/secondary? I have a multi-meter but don't know where to test or if the bike should be running or not while testing.
Any ideas or a direction to start poking around would be much appreciated. I know nothing of carbs so I want to stay away from those if I can.
