Best engine kit to use???

[Biggdaddy]

Hello All,
Wife decided she wants me to put a motor kit on one of my flipper bikes to see how it sells at the shop (Like I don't have enough work to do already). Anyway I have never done any research on these kits do any of yall know which ones are good and which ones to stay away from? I do not want any junk going out of my shop so I'd really apreciate some good input. Thank You in advance.

My research leads me to believe KTM has the best 49cc, but I am no expert.
Whatever you use do the crankshaft conversion, it looks so much better.
