beedys have the older mallossi timed at 18btdc , i think for safety on the newer one i'd start at 16btdc an see where its at .
check the large frame set up page on "German Scooter Forum" , 221's with 30mm carbs run from a 128 main upto a 145 on there . the lower ones are older set ups an i'd expect this motor to be around the higher number mark . H

Why the low comp head? And why the long gearing? Will it be for touring on?
