LF200 chain followup
 

Im sorry I didnt clarify in my previous post. The bike I have right now is a Lifan LF200, the "sports bike" lifan. Im buying a LF200GY-5 in about a month, but I use the LF200 for commuting and need more top speed. The stock rear sprocket on the LF200 is 40 teeth! I know this is a dual sport post, but I was wondering if maybe someone knows something about my model also. They also sell this bike as GRX200 and Razor, comes with the OHC 200cc motor but like I said, the stock sprocket setup seems to be different from the GY-5 model.
