So far so good. Noticeable more power
Seems to be built well, very simple to install and adds a noticeable amount of power.

Some… but not much
Horsepower gains were less than expected but still a good quality product.

Easy to install and worth the $. It was a great upgrade for the power
So far I am extremely happy with this kit. My 7 year old son has not shut his bike down for a whole week up to this point. The kit was very easy to install and has all the required parts needed to literally just bolt into place. This kit added quite a bit more power then the original 50cc. Great value for the money.

Great value for the money!
The media could not be loaded. Easy to install and runs great. These are the best (other than oem) top end for a pw50 or zinger. Fits perfect and starts right up. Has plenty of power and is a good value.

Ok if you can hone it.
Piston was tight, had to hone it to fit properly. Buy a rigid hone too if you buy this
