Its already got a bbk from the factory. These are whats called the K-block motors. A-block is the older gy6s...gy6B has the bigger spacing and different crank and different cvt.....B-block is a custom case with the gy6b spacing in an A-block case....K-block has the gy6B crank and variator with a 5mm smaller rear pulley and different belt. K-block has the gy6B and B-block stud spacing but the two smaller bolts on the side are spaced diffenetly so the B stuff wont work.

Does your manual have a parts list with part numbers in it?
