I have the delorto on a Malossi 70cc kit, I did have to buy their choke kit, and you have to modify the throttle cable as shaka said. All in all, I wish I had bought another brand. The screw cap on the barrel is a GREAT time saver when tunning. I had to loosen the carb. ,tilt it 45%, remove 2 tiny screws, just to adjust the needle.
