52.4mm Engine Parts Cylinder big bore kits with Gaskets and Piston Set for 4 Stroke Chinese TaoTao Coolster ATV 110cc Pit Quad Dirt Bike Go Kart

Bought this for my 110, they stored the piston inside the cylinder, with no oil or no rings, so the side of the piston was scratched. The oil feed hole was also filled with casting sand, and the head gasket was all mangled and bent, and the red seal line was broken in a few places.

Bought a whole rebuild kit and only thing it came with was the cylinder bore and that's heavily damaged !!!! Missing all other parts!!!! Was thrown in a box with plastic bags.

Purchased this for db10 with hard starts and a lot of smoke. The cylinder didn’t fit due to in trimmed air cooling fins to fit around the starter. Used the old cylinder since it still had decent cross hatching. Piston worked out well though, and bike it back in working order.

Returned last cylinder for crack and bend in bottom of bore. Just opened the replacement and cracked again. Roll the dice maybe you get a good one

Quality of the piston and gaskets is great, the cylinder... not so much. I didn’t see any defects before installing but after it was all together it started leaking oil from a hole between the cooling fins on the first start. Waiting on the company to respond..

Fast shipping but does not fit a 2000 Yamaha TTR 90

Cylinder inner surface was damaged and had some hack of a honing job. Piston shipped inside of cylinder with no protection cylinder and piston was scored gaskets were shipped with no protection and was also damaged.

The oil hole looks really rough and is not concentric with the gasket. It was also packaged poorly and broke in transit, which was two days late BTW.
