Am I supposed to block off the breather holes on the head, right below the carbs? There are 3 holes 1 plugged(nonCA model) 4 holes with cA model. I finally got my bike runnign and had done the mod but the bke runs like crap. It won't idle and is running on like 3 cylinders. If the choke is taken off it will die, and have tried to adjust the idle. Any thoughts?
