YX Cylinder Heads Editorial Review

The YX 140CC 2 valves Engine Head Kit is a stock replacement head that does not increase the engine's displacement. It is compatible with 56mm bore and 57mm stroke engines and comes with a fitted Z40 camshaft. However, there have been some issues reported by customers, such as missing parts like the oil cooler plug, valve seats, and oil passage tube. Some customers also experienced bent bolts, loose cam gear, and unsatisfactory performance. On the positive side, it has shown noticeable power increase when paired with a 141BBK kit.
