Does opening out to 6 turns richen or weaken the fuel/air ratio? I would assume (hope) the former given the quote above. My gut feeling is that its too weak at that point.Raising the needle might also help. That should be possible with out removing the carbs?

Got chatting about 660 motors and I was told by one long time (from new) Mastiff owner that all of these models tend to pop/bang as standard - something he just puts up with. He also said the Skorpions do not seem to suffer from this problem even though they appear to have the same motor and carb. Don't know what if any difference there is in the jetting between the Baggie/Mastiff and the Skorpion.
