Is a flat slide carb faster than a VM22 on a Coleman CT200U-EX? Ran the 196cc powered Coleman CT200U-EX minibike at top speed and zero to thirty with the VM22 Mikuni carburetor on the 196cc engine, and then swapped it out for a 24MM flat slide carburetor and did the same test to see if there was any difference in performance I.
