Been working on a Cady M1PR 1974.
I’ve modified the original 10mm intake to accept a larger intake pipe onto the flange by cutting off the original and then grinding smooth with my dremel.
I then proceeded to enlarge the intake hole on the flange to increase flow. My hope is to weld on 3/4” o.d. pipe as the carb I’ve ordered is .76” clamp style attaching.
Hoping in increasing the power from 33kph to hopefully 50kph if I’m dreaming.
