So I found this site selling upgrade kits for many of the Chinese bikes. They claim to actually do dyno testing to show the improvement to expect. They also have good tutorial videos showing how to install.
I did a search and found no mention of them here on the forums. Does anybody have any experience with this company?
I have a Hawk 250 and am thinking about doing the basic kit... mostly for fun.
