Balancing and setting up cant be any harder than fiddling about with an early A7 Star Twin duel carbs, with pre monoblocs. With a proper carb balancing kit the job is easy and once set up right should then be left well alone. I'm happy with my set up and although not a great noticeable difference in power, it is a great talking point! Someone will get an amount of pleasure out of this along with a painfully empty wallet as it wont just be the carb thats likely to go up in price, but also the purchase of another carb and internal parts to match each other.
