Found a vintage Henry Abe 900 kit and am building a 750/900. I am using a 1974 motor. Urban myth has it that the 900 over heated. My feeling is you need to use a bigger cam for better breathing so I got a mildly bigger cam. Also obtaining stiffer cam springs. Motor is now apart and cleaned, big sleeves are in the cylinder, bought the rubber sleeves to use a set of 29mm smooth bore carbs. Plan to do the hold down screws in the cam cover. What else should I do? Not planning to race the bike, just want a more powerful street bike.
