awesome!!! I bought the Honda GXH50UQXA and it is the best quality engine I have ever owned. casting and machining are perfect, no seams or gouged metal. great quality made in japan. i bought this engine for a motored bike and the kit fits perfectly on it and moves smoothly. the engine has great features. the governer system is engineered well, the cylinder walls are thick and fins are mint. very good looking engine all around. the shipping was great, was at my doorstep in 4 days. packaging was great quality enshured that the product was safe in shipping. I would most certainly recommend this engine to a friend and in the near future plan to buy more. Thanks northern tool. Jon January 31, 2008
