Need some help choosing the best bang for the buck . I have a very very slow Kx 65/72cc in a Aprilia RS50 . Stock 24mm 65 carb . Looking at 28-30 mm carbs and have used Lectrons on drag bikes with no experience on a road bike . I see I have options from a $25 knock off which will probably be more trouble than it’s worth to $500 ++ smart Carbs . Is the Mikuni 28 mm at 1/3 of the cost of Lectron just as effective for a slow old guy ?
