If you order this 57mm bore kit for 150cc gy6, I would purchase another 57mm piston from a company that manufactures quality pistons and rings. If you choose to use the piston and rings in the kit, in about a week of constant riding the piston rings will break and you will be taking everything off again to replace those rings, it’s time consuming and sucks!! A good quality piston and rings will cost you no more then 25 bucks with shipping at gy6Racing

Though this says it will fit a 157qmj the cylinder and the head will not fit,they will fit the stud bolts,but the holes to mount to the block,the left side lined up but the right side was off a few mm making it impossible for them to be used,all of the gaskets that came with it,with the exception of 1 was either too big or too small to fit,they was so far off that they couldn't even be made to fit,on top of that,they expect me to pay return shipping which would be about half of the cost that I bought the kit for,so I'm stuck with a rebuild kit that I can't use,out of what I paid for it because they are selling defective parts and expect me to pay to have them shipped back
