We are headed to the mountians this weekend. Need to adjust tonight. The blaster is stock so I would guess the needle is set to 3 (middle). For this ride we will be mostly putting around. Do I need to adjust the needle? Can I just get away with taking off the air box lid? Or even just the snorkle on the air box? Hate to tear into the carb with the oil injection crap in the way. (need to rid that mess anyway)
