It suits Chinese pit bikes. Buyers will receive one cylinder head as pictured. This item comes complete exactly as pictured and ready to use but it is advisable to check the tightness of all bolts prior to use, as we cannot be responsible for mechanical problems caused as a result of unchecked fitment. Please check your existing cylinder head prior to purchase to ensure that you are ordering the correct type for your machine. Key things to check are the distances between head bolts measured centre of eye to centre of eye, the timing chain sprocket and the engine number compatibility code where listed.
