Chains are a weak link with Chinese bikes. You will probably want to replace it. As far as manual transmission, you will probably be better off with an entire engine. Many people replace the common 125cc engines with 140cc, 150cc, 160cc or bigger. That includes pitbikes. So, my guess is there are quite a few stock manual trannsmission 125cc pitbike and CT70 replica engines around for cheap. I have a feeling there is no easy way to swap out just the transmission.
