Came as described.VERY comprehensive kit for a do-it-yourself moped! The listing requests a bike frame with approximately 1 inch diameter tubing to fit the motor mounts best, but we didn't have that, ours was much girthier. So I ended up making a couple of simple brackets to allow for the fatter frame tubes. (I'm a welder and fabricator, this is NOT easy for the average rider) Once I made the custom brackets for the mounts, everything else on the kit installed exactly as the manual showed (which does have very small pictures, so a magnifying glass helps!). I did have to purchase a chain-breaker, since the included chain was about 8 links too long for our application. Note: it is a size "41" chain. After installing the chain and the adjustable tensioner, I noticed that the tensioner pully didn't line up with the direction of the chain, because it is mounted on a frame tube that is angled slightly differently than the chain. To account for this, I tweaked the tensioner bracket a little so that the pulley spun in line with the chain, and it worked really well. The kit comes with a spark plug wrench, an allen key wrench that fits the side cover bolts on the engine, and doubles as the handle for the spark plug wrench, and also an interesting threaded nut assembly that is meant for pulling the sprocket off of the clutch. This means that much of the maintenance of the engine has the tools covered. That's a nice touch, thank you!RIDING: I want to start by saying, I AM A LARGE FELLOW. I weigh about 240 pounds. This little engine really impressed me, since during the break in, it ran very smoothly at about 20mph, and was able to get a fair bit higher than that (paced by my friend in a car, the bike is a 26 inch model). The engine noise was less than I would have guessed, since many of the mopeds in my town are much louder than this. On a 20-30 minute ride, it wasn't overpowering, the vibration was acceptable, and it JUST RAN!The only question is longevity. I've owned many 2 stroke engines over the years and am versed in getting the proper petrol/oil mixtures, so we know the engine will have the fuel that it wants. I plan to update the rating in a few months with my report of how it's doing in the longer term. The owner will probably be riding it as a daily driver for work and errands, so it will get a LOT of use in the next few months. Currently the rating is 5 stars. If it is still 5 stars, then it's either still running strong, or we haven't updated it yet.
