    Hi all, I've had my Huasheng 4-stroke bike for a while now, and I use the 32-tooth sprocket with it. It gave me about a 5mph boost over the stock one, but I see people on here and YouTube boasting about their 30-40mph bikes?? How does a guy go about getting that kind of speed from the 4-stroke? I looked into a shifter kit but it's just too expensive for me to justify getting it. So what do you guys recommend for aftermarket parts to get me going faster? Thanks a ton!

    Jackshaft kit. You can upgrade parts but it won't gain you much more speed. Either custom build a 4 stroke bike with a predator that can go 40mph or stick to 30 max without a jackshaft system.

    What was the stock sprocket size, 44 tooth? If so you may have went too far. The little engines need to run at a higher rpm to perform at their potential. A 36-40 might be a good compromise.
