Note: The models this kit fits are called "550" but the engine size is actually 499cc. Make sure your cylinder it says "499cm3" on it. The CF188 is a CFMoto 500cc engine that looks very similar to the CF191R but is not the same, make sure your engine type is CF191R. The CF191Q (400/450) version of this engine looks identical and even has the same size bore (91mm) but the cylinders cannot be interchanged because the 500cc engine has a longer stroke.
The kit fit correctly and included everything needed for the rebuild. The engine regained strong compression and now runs smoothly with plenty of power.

Check your piston. This one was an exact match for my engine. This one lined up with the valves perfectly. Others had different valve profiles in the piston.

When I first rebuilt my gy6 150cc motor I had low compression and excessive oil in the cylinder. I tore the engine apart again and found that my piston rings were installed upside down. I flipped them over the right way and the engine has 155psi compression and no oil problems. The motor runs great after 3 hours or so of run time. You DO NOT need to bore the case on your motor with this kit which as also really nice. You will almost certainly need to rejet your carb. I used a #125 main jet with this big bore kit, performance head, nibbi intake, and straight through exhaust.

It was quite the job to install it this product, not due to the quality of it being aftermarket, because the job itself was really difficult.
However, I’m happy to report immediately after installing this replacement cat my sisters mpg was immediately restored to full capacity and her check engine light went off immediately!
LISTEN TO THIS PART!
IF YOU ARE PLANNING ON DOING THIS JOB MAKE SURE YOU KNOW WHAT YOU ARE GETTING YOURSELF INTO IT
IT WAS A VERY HARD JOB FOR A HOME USER
but it’s a good product!

Fit 2016 Kia Soul Base. My OEM cat cracked and replaced it 1 1/2 ago with an eBay knock off...Mistake, check engine light would not go off. This one after 35 miles the Check engine light went off and was able to pass emissions. 🎉 Heat shield fit to the original OEM bolts unlike the eBay one that I had to redrill and use smaller bolts. Included all nuts, bolts and gadgets. Much better build quality than the eBay junk. Lets see how long it will last. 🤞
