The bore surface arrived smooth and evenly finished, with clean edges around every port. Assembly went together without binding, and compression feels strong throughout the kick stroke.

Compression came back strong after the rebuild, and the ATV starts with much less cranking. The cylinder surface was clean and ready for assembly right out of the box.

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.

Choosing a selection results in a full page refresh.
Compression feels even again, and the engine pulls strongly during steep climbs. The gaskets remain dry after several heat cycles, with no visible oil smoke from the exhaust.
The mounting holes aligned with the factory points, and the plate sits firmly beneath the radiator support. It clears the surrounding panels properly, with no vibration or rattling on uneven roads.
After the overhaul, drive and reverse engage promptly without the previous delay. The seals fit their channels correctly, and shift pressure remains consistent through every gear.
Commanded and actual fuel pressure now track closely during acceleration. Idle remains steady, and the engine pulls under load without surging or sudden power loss.
