44 tooth Sprocket for Qingqi QM200GY-BA (Qlink XF200)
First of all, are you sure that you have the Qingqi or Pioneer bike?, In 2006 Qlink changed their XF-ranger from the Zongshen made Yamaha TW200-clone to the Qingqi or Pioneer Suzuki-based bike named XF200.
The Qingqi / Pioneer Suzuki-based model looks like this:

The previous model, made by Zongshen looked like this:

Assuming that it is the Qingqi model and you have the 428 size chain on yours, the correct Suzuki part number for a 44-tooth sprocket is:
64511-48700 It fits models: TS125ERN / ERT / ERZ
And if you want to get it from JT Sprockets, the number is JTR809.44
However I've found great difficulty in finding this and instead part number 64511-48001 also 44 tooth and for a DS100,DS125, TS100, TS125 (1978-79) will also fit.
the number you've quoted for the 42 tooth one is should be correct, but I fear the gearing will be too high for the power output of the bike. I could be wrong though.
To ascertain what chain you have, measure it: The 428 chain has a 1/2" pitch and the 520 has 5/8" pitch.This is the measurement between pins or rivets.
The dimensions of the sprocket are:
