    Hello all!

    Yamaha rd250 1974. I'm getting a weak spark from one plug but not the other. Weak enough not to fire that cylinder. If i switch the coils around, the strong spark switche's to the oppisite side. I replaced the points, condenser, coils and new battery. Just cant seem to figure this one out? Could this be a problem with the rectifier and or voltage regulator?
