Mukuni 28mm FLAT SLIDE carb. When you have out grown your 26mm round slide carb, this will be the next step before you go with the 28 D SLIDE carb. We have found this carb to be very easy to tune and seems to be a little easier to run than the D Slide unit. Very quick throttle response as well as advances the torque curve , over the 26mm round slide units. Uses the same throttle cable as used for your 26mm round and 28 D Slide. Comes with a 180M/15P
jetting. This seem to be the best starting spot for the 124 bore
motors.
