i dont have that kit but i have that exact engine, its a 49cc motor true to the name and its a clone of a mitsubishi motor. they run pretty good and have lots of power, mine is on a skateboard and i can get up to and over 40kph. hill power is good too, i had this engines little brother too. it looked identical but was 33cc and physicaly allot smaller, it ran great for years until the intake gasket melted away and it got an intake leak then dropped the wrist pin rollers into the crank at 8000rpms. so if you do get it make sure you change the gaskets, also make sure you replace the bolts holding the engine to the frame. there cheap and once on breaks then the engine casting will crack and the motor is worthless, but the clutch and transmissions are very good and quite reliable. i cant speak for the rest of the kit though because it may not be made well.
