Hi Askebre and welcome to the forum. I would stick to 21. What are you looking for exactly - outright performance (top speed and acceleration etc) or longevity and more mpg because this will affect your decision at the end of the day.
When tuning a 2 stroke, fuel usage is bottom of the list for most people. Interested to see if anyone has any info on this. I suspect the smaller carb uses less fuel in low range revs and bigger uses less in high revs.
If youre new you should consider buying a less powerful cylinder like stage6 street race or dr evo 70. The racing mk2 likes to seaze on poor jetting and doesn't forgive mistakes.
Which pipe you running? Race pipe go 24, sane pipe go 21. MPG no idea, if your going to commit to a MK2 racing, you need a big carb and racing pipe. MPG is the least of your worries.
