I built a gy6 150 into a 193cc I believe? Any how I am having a problem with it clacking like a knock when I rev it fast. I’ve got a 61 mm cylinder and head from taida with a 8.2mm stroker crank. The crank came with a 92 link chain I’ve seen nothing but 96 link chains for 8.2mm cranks. Is a short chain going to cause my problem?!?
