Just finished a re-install of carbs that have been rebuilt. They have been twice checked on a test motor and are fine. Bike was still not smooth. Today I noticed the exhaust on right side was not warm. Started feeling the pipes moving toward the motor--pipes not warm at all. Left side is hot as normal. Evidently right side is not firing---has NEW coils. I am at a loss for ideas. Anybody else ever encounter this kind of issue??
