description was perfect, although I had one problem when they ship it, they installed the screws in the grooves of the airfins that provide cooling and it got all scratched up and **** **** I was very unhappy about that and because of the scratches I'm not going to use this for what I thought. Instead I'm going to save it as a backup in the event I need to replace the jug in piston.

The engine runs more efficiently, and there’s a noticeable improvement in acceleration. It feels more responsive, and the difference in performance is significant, especially for an aftermarket replacement. This cylinder head is durable and feels like a quality piece that’s built to withstand demanding use.I’ve taken my bike out for several rides since installing the WOOSTAR cylinder head, and it’s been holding up wonderfully. There’s no overheating, and it has improved the overall stability and performance of the engine. The materials seem top-notch, and I’m confident this replacement part will last a long time.In conclusion, the WOOSTAR Big Bore Cylinder Head Replacement is a worthwhile investment for anyone looking to enhance the performance of their YinXiang 140cc engine.
