I don't want to be the guy who makes noise with no issue, but it seems all the sellers of these engines are in you figure it out yourself mode.thothese little engines are not a hard install, why the hedging about simple diagrams or some hand drawn details even for these items?Seller, not everyone will part with the fee to have these things put together.

Arrived in double box. With intake manifold, side cover, 13T sprocket, and spark plug. Mine did come with the 5 wire harness and I had prior bought the adapter for my application. Will make my wiring neater for my Amstar 50 swap. My wire colors match up nicely. Overall happy with packaging and motor turns freely by hand. Will update after install. Marked 154FMI (aka 125cc) though included emissions sticker on box says 107cc?? Anything has to be better than my 50. LoL

This thing takes some serious abuse, would buy again! If you buy this for your 5 year olds atv I don't think it would ever die.
