this is my latest bike. i build this one for speed, i will get videos when i can. i have a motorboys 66cc engine with an expansion chamber, port and polished and a 36t rear sprocket. i have 140kms on the engine and am now leaning it out. it will do 0-40 in about 6 seconds if i pedal from dead stop and i can top out at 60 on the flats. i am hoping to break 70 once its broken in and everythings running perfect, anyways here are some pictures
