Outstanding!!!
This is the best aftermarket top end kit I've purchased. It installed like it was supposed to and more importantly, the bike runs like new. I did have to fine tune my carb settings, but after that....the bike runs and idles perfect! Very happy with the parts. This kit is only for the later model Z50s that have the flat top pistons....it will not work in the old 50s that used the old domed pistons.
I saw a YouTube video about this product after I bought it. In the YouTube video, the wrist pin was too large and would not work with a Piston. The kit I got all works. The piston is not very good quality. But for the price it’s worth it just to get it for the cylinder.
put it on a stock xr50 and it was good compression. bike is running and idling good now. have about 10 hours on it and no smoke.
