Hi everyone. I've got myself a cheap track bike that I basically revived from a rusty death at my friend's old apartment and I'm verrrrrrry excited to put on a bicycle motor. From what I've gathered so far, I want a 66/80cc motor from either "Jet" or "Black Stallion" from KingsMotorBikes.com. If anyone has any history with the folks at KingsMotorBikes.com and can tell me successful or failed stories, I'd really appreciate it. Also, what are YOUR opinions on the Jet or Black Stallion motors and which would you personally prefer? They're only $10 apart so I'd rather get the better-liked of the two. LASTLY, here's a few photos of my bicycle. UNFORTUNATELY, I do not know the specific dimensions, but from the looks of the photos, do you think I would have any problems? Thank you!
