Scooter 150cc GY6 Engine Rebuild Kit Cylinder Kit EGR Cylinder Head 157QMJ

Make sure you understand if you have an EGR / Pair System setup on your engine or not. If you currently don’t have EGR, this is not the rebuild kit for you. You can make this work with a non-EGR engine but you will need to purchase an EGR valve cover and mod / weld the EGR pipe closed. Didn’t realize this was the wrong setup until I was completely rebuild and installed. If you make the same mistake that I did, it is correctable but will require a bit more time and money. There are several videos online on how to remove EGR from Gy6 engines. If your rebuilding the engine you can likely do the mod if needed. Kit wise, everything was there that I needed.

This kit is absolutely terrible. I lost so much power and wasted hours of my time installing it. After a compression test I came up with almost no compression. Bought different kit elsewhere and had great results.

Came early everything was there my motor is EGR but it's not on the motor it's on the exhaust so the head is incorrect but I'm going to modify it satisfying

My kit did not have the valve cover gasket that is shown in the picture. Other than that it was all good.

the product was good,the main problem' was then piston rings not being cut correctly .

Everything seemed to fit just fine it runs really well but there is some kind of emissions Port coming out of the exhaust by the valve cover which none of the six motors I've built in the past have had this so I did have to pull the head back off because I did not notice it at first and run a tap in it and put a plug.
