Hey there I have a cranny with a skyhawk GT2 (I believe) It's 48ccs and I do have the "new" performance carb with the red filter on it. I don't have any bogging issues I fixed that by taking off the black vent tube and It really put new life in it. I don't really know the max speed I can go because I don't have any way to gauge the speed but I believe it should performing better. It seems like it can do about 25mph. Am I expecting to much out of my bike or am I experiencing Issues. Any ideas on how to tweak the carb by missing around the idle and mixture screws...or whatever. It has plenty of fuel. I could just be tripping and lost that first month of like "wow this is fast" feeling.
